Renamed and moved a couple of I/O utility functions
This PR renames/relocates the following methods and variables:
-
gwpy.io.cache.FILE_LIKE
->gwpy.io.utils.FILE_LIKE
-
gwpy.io.cache.file_name
->gwpy.io.utils.file_path
-
gwpy.io.cache.file_list
->gwpy.io.utils.file_list
and updates their usage and tests throughout the package. This is backwards compatible (the new names are imported to their old locations, with appropriate DeprecationWarnings
).
