Type inference of file types

[multimeric]

e.g., look for arg.fasta which indicates that the CliFile is a fasta file.

This should become a new field on the CliFile class:

CliHelpParser/acclimatise/cli_types.py

Lines 86 to 91 in 435e560

	class CliFile(CliType):
	"""
	Takes a file path
	"""
	pass

.

Parsing should be implemented in <FlagArgSubclass>.get_type and/or infer_type:

CliHelpParser/acclimatise/model.py

Line 382 in 435e560

def infer_type(string) -> typing.Optional[cli_types.CliType]:
