[FEATURE] Create a wrapper for L0 readers click commands

[ghiggi]

Is your feature request related to a problem? Please describe.

I think the code readability of the L0 readers would improve if we manage to compact reduce the list of click commands
that are present above the reader function definition

Describe the solution you'd like

Follow this approach

@click.command()  # options_metavar='<options>'
@click.argument('raw_dir', type=click.Path(exists=True), metavar='<raw_dir>')
@click.argument('processed_dir', metavar='<processed_dir>')
@click.option('-L0A', '--L0A_processing', type=bool, show_default=True, default=True, help="Perform L0A processing")
@click.option('-L0B', '--L0B_processing', type=bool, show_default=True, default=True, help="Perform L0B processing")
@click.option('-k', '--keep_L0A', type=bool, show_default=True, default=True, help="Whether to keep the L0A Parquet file")
@click.option('-f', '--force', type=bool, show_default=True, default=False, help="Force overwriting")
@click.option('-v', '--verbose', type=bool, show_default=True, default=False, help="Verbose")
@click.option('-d', '--debugging_mode', type=bool, show_default=True, default=False, help="Switch to debugging mode")
@click.option('-l', '--lazy', type=bool, show_default=True, default=True, help="Use dask if lazy=True")
@click.option('-s', '--single_netcdf', type=bool, show_default=True, default=True, help="Produce single netCDF")
def main(raw_dir,
         processed_dir,
         L0A_processing=True,
         L0B_processing=True,
         keep_L0A=False,
         force=False,
         verbose=False,
         debugging_mode=False,
         lazy=True,
         single_netcdf = True, 
         ):

would become

# Define this in some file
def readers_click_options(function):
  function = click.argument('raw_dir', type=click.Path(exists=True), metavar='<raw_dir>')(function)
  function = click.argument('processed_dir', metavar='<processed_dir>')(function)
  function = click.option('-L0A', '--L0A_processing', type=bool, show_default=True, default=True, help="Perform L0A processing")(function)
  function = click.option('-L0B', '--L0B_processing', type=bool, show_default=True, default=True, help="Perform L0B processing")(function)
  function = click.option('-k', '--keep_L0A', type=bool, show_default=True, default=True, help="Whether to keep the L0A Parquet file")(function)
  function = click.option('-f', '--force', type=bool, show_default=True, default=False, help="Force overwriting")(function)
  function = click.option('-v', '--verbose', type=bool, show_default=True, default=False, help="Verbose")(function)
  function = click.option('-d', '--debugging_mode', type=bool, show_default=True, default=False, help="Switch to debugging mode")(function)
  function = click.option('-l', '--lazy', type=bool, show_default=True, default=True, help="Use dask if lazy=True")(function)
  function = click.option('-s', '--single_netcdf', type=bool, show_default=True, default=True, help="Produce single netCDF")(function)
  return function 

## In each reader 
#  Add the import of  readers_click_options
# And modify as follow
@click.command()
@readers_click_options
def main(raw_dir,
         processed_dir,
         L0A_processing=True,
         L0B_processing=True,
         keep_L0A=False,
         force=False,
         verbose=False,
         debugging_mode=False,
         lazy=True,
         single_netcdf = True, 
         ):

@regislon can you take care of that?
Related to this refactor ... do we maybe want to change the name of the function? From main to reader
