Added get_local_node_and_timestamp() for timestamp versions

[engnadeau]

Affected Issues

• Fixes Allow custom timestamp for get_local_node_and_date() #200

Proposed Changes

• Added function get_local_node_and_timestamp(version, fmt='%Y%m%d%H%M%S')
• This function is callable as is (e.g., get_version(local_scheme=get_local_node_and_timestamp)) or as an entry point (e.g., get_version(local_scheme='node-and-timestamp'))
• Wrappers can be built around this function to provide custom timestamps, see examples below:

Example Usage

Using Entry Point

v = setuptools_scm.get_version(root='..', relative_to=__file__,
                               local_scheme='node-and-timestamp')
print(v)

Using Callable

v = setuptools_scm.get_version(root='..', relative_to=__file__,
                               local_scheme=get_local_node_and_timestamp)
print(v)

Using a Format Wrapper

def min_timestamp(version):
    return get_local_node_and_timestamp(version, fmt='%Y%m%d%H%M')


v = setuptools_scm.get_version(root='..', relative_to=__file__,
                               local_scheme=min_timestamp)
print(v)

def micro_timestamp(version):
    return get_local_node_and_timestamp(version, fmt='%Y%m%d%H%M%S%f')


v = setuptools_scm.get_version(root='..', relative_to=__file__,
                               local_scheme=micro_timestamp)
print(v)

this should use nested replacements as per https://www.python.org/dev/peps/pep-3101/#format-specifiers

this needs an api addition however
