Mkbak

- Removed '-u|--unbak' until it's complete

Released 2021-03-01

- Progress bar added when copying or deleting files
- Removed excessive indentation
- Opening of directory to search switched to older open/close to remove another
level of indentation
- Argument handling moved to `mkbak_args`

- Bugfixes
- `--no_sort` now works
- Better value-checking with `--height` and `--padding`

- Global variable initialization moved to `__init__.py`
- Project structure changed
- .pyi files added
- py.typed files added
- Argument parsing moved to module
- Arguments stored as a dictionary (as opposed to argparse's Namespace object)
for consistency in setting variables. Previously, some values would be renamed
and some would be passed to `iterfzf` as is, but the dictionary allows values to
be changed in place

- Errors are more verbose and suggest fixes based off of the issue that occurred.
- Bugfixes:
- Files will now properly reflect if they were successfully copied BUT unable to have their ownership changed

- `mkbak-iterfzf` version upgrade
- Added `ansi` option
- Added `bind` option
- Added `no_sort` option
- Added `padding` option
