Add a Replay speed control feature (#1106)

## Description:
PR for https://github.com/openfrontio/OpenFrontIO/issues/1105
This pull request introduces a new replay-panel under options-menu to
control singleplayer and replay speed.

User can select 4 different speed multipliers based on the
turnIntervalMs config.

I locally tested the feature in singleplayer mode. I couldn't find a way
to test replay mode.
Tested with the pause button, working as you would expect.


Here is an example:

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
⚠️ I need help to test this feature in real conditions with a replayed
game in dev env.

- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors

## Please put your Discord username so you can be contacted if a bug or
regression is found:
