## About The Pull Request
This adds a ignition sound whenever a fireplace or bonfire is initially
lit on fire. Afterwards a continuous burning loop is played. Also added
some documentation and optimized fireplaces to only `process()` when
lit.
## Why It's Good For The Game
Better consistency.
## Changelog

sound: Add burning sound loop to bonfires and fireplaces
code: Improved fireplaces to only process when lit
