Lowbar

- Minor patch that removes an unnecessary f-string

- PyPI re-release with fixed README

- Added `no_clear` parameter, which if enabled, will prevent the automatic clearing of the bar when exiting from an iterable or context manager.

- Added `bar_desc` option, which will display a description beside (left) the progress bar. The description will be hidden if the console size is too small to accommodate both the bar and the description.
- Added `remove_ends` option, which removes the two chars (`[` & `]`) used to define the two ends of the progress bar.
- Added extra checks to make sure `bar_load_fill` and `bar_blank_fill` are single char strings.
- Reduced sleep call duration in `update_smooth()` from 0.005 to 0.002.

- Fixed broken update (1.4.1), `bar_iter`'s default value type set to int instead of NoneType

- Automatically convert `bar_iter` to a range object if it's an int
