Dolphie

After releasing 3.0.5, I realized `R` command crashed Dolphie. This small version fixes that plus a few cosmetic changes to the bordering of Replication panel.

**Full Changelog**: https://github.com/charles-001/dolphie/compare/3.0.5...3.0.7

- Replicas/Replication panel got a bit of love:
- Errant transaction GTID support for replicas
- Shows full `source_id` instead of the last part of the server's UUID
- Width of each replica table is more optimally sized and all replicas are now wrapped in a border to easily differentiate them
- For MySQL 8, we now have a new table beside replication table that displays the performance of applier threads (18)
- Replication now has a few variables displayed at the top of its table (18)
- Replication will now include in its table fields like `Replicate_Do_DB`, `Replicate_Ignore_Table`, etc if they're set
- Cosmetic changes
- Fixed support for Python 3.8 (17)
- Dolphie will now continue to intake metrics when the main screen isn't active. Before, it stopped and there would be a gap for the duration it wasn't active
- Graph switches are now remembered when using quick host switch since they were being reset

Hope you enjoy!

- Bug fixed that prevented Dolphie from working with RDS/Aurora (16)
- Dashboard has a few more datapoints added to it
- Header now uses hostname from MySQL instead of the host you specify to connect along with its port (15)
- Quick host switch now supports port
- Fixed quick host switch so it now adds new servers to the autocompletion list instead of having to restart Dolphie
- Replication panel now shows the IO and SQL thread state
- URI is now a positional arguement at the end instead of using `--uri` (14)
- Numerous help verbiage changes

- Event log (`e` command) now supports search and has hotkeys to go to the bottom of event log and back to the top. It is also now a lot more efficient due to the use of Textual's DataTable widget
- Added URI string parameter `--uri` for supplying credentials
- Added transaction history when looking up a thread via `t` command
- Added plugin and password expiration fields for `u` command

Thanks to lefred for his suggestions!

Big release today! I've re-written Dolphie to use Textual which has opened a lot of doors for what's possible. You'll notice it's faster, smoother, more features, and overall just _alot_ better.

One big new feature that I'm proud of is the graphs. I hope you find them as useful as me :)

If you have any suggestions or issues, please let me know!

- Added `m` command: Show various memory allocations
- Added `E` command: Show error log from performance schema
- Fixed explaining queries with comments
- Fixed lag for each replica in the replica view
- Byte sizes now have a B after the suffix to differentiate from number formatting
- Host name is now in the header
- Help command is now using a pager so it's easier to read and can be easily scrolled with arrow keys
- Various code cleanups
