Add naval combat animations (#858)

## Description:


https://github.com/user-attachments/assets/b46f949a-eb50-4656-8492-216cf820ac46

Add a couple animations for naval combat:

- shell hit
- ship explosion
- ship sinking

Added a simple `Timeline` class to spread FX animations over time.
Added a `ColoredAnimatedSprite` similar to the existing `ColoredSprite`.
Refactored the latter to avoid code duplication.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors
