Rotala first release

Project is renamed to Rotala. Provides an HTTP client/server for running backtests.

Uses the same backtesting engine as alator but rotala contains none of the higher-level logic, it is just the exchange.

Provides two exchange implementations:

• Uist - this is essentially the same as the exchange implementation used in alator, available as a library and http client/server.
• Jura - this is a partial implementation of the Hyperliquid exchange, available as http client/server.

Changelog contains the preparatory changes which were made up until Rotala switchover, this happened at PR #52 (iirc).
