Fdiff

- Added support for OpenType table include and exclude filters - `fdiff` executable: added `--include` option and defined comma delimited syntax for OpenType table command line definitions - `fdiff` executable: added `--exclude` option and defined comma delimited syntax for OpenType table command line defintions - `fdiff` executable: added validation check for use of mutually exclusive `--include` and `--exclude` options - Library: added new `fdiff.utils.get_tables_argument_list` function - Library: updated `fdiff.diff.u_diff` function with new `include_tables` and `exclude_tables` arguments - Library: added OpenType table validations for user-specified name values in the `fdiff.diff.u_diff` function. These checks confirm that at least one of the requested files includes tables specified with the new `--include` and `--exclude` options

- Initial release with support for the following features:
- local font file unified diff of OpenType table data dumped from the font binaries in the TTX data serialization format
- ANSI escape code colored diff renders with the `-c` or `--color` command line options
- Custom version of the third party Python standard library `difflib` module that includes a modification of the "autojunk" heuristics approach to achieve a significant unified diff performance improvement with large text files like those that are encountered in the typical TTX dump from fonts

- pre-release version that did not include executable source code
