* default layouts won't be installed by anymore,
instead they will be directly loaded
* `layout-dir` is now a subdirectory of the
`config-dir` by default, instead of the `data-dir`
POSSIBLE BREAKING CHANGE:
In case of having custom layouts in the previous
`layout-dir` one can switch either the layouts to
the new dir, or set the `layout-dir` to be the current
`layout-dir`
* it is possible to change the location of the `layout-dir`:
- `zellij options --layout-dir [LAYOUR_DIR]`
- `layout_dir: [LAYOUT_DIR]`
* send all tabs in vec
* works but no input filtering
* add event types
* add event handler for tab events
* fmt fixups
* update tab name in place, and escape rename works
* rename handle_tab_event handle_tab_rename_keypress
* handle empty new_name when renaming
* fix(tabs): pad active tab name too
* fix(tabs): report proper length
* fix(tabs): always render active tab
* style(fmt): rustfmt
