refactor: Rate limiting guard should track the calculated HTTP requests and add `is_available` to exchanges and forex sources to clean up feature flag check. #134
The rate limiting guard now takes the number of HTTP requests needed instead of the number of rates needed. This moves the calculation out. This also fixes a bug when IPv4 support is not available causing more requests to be reserved than required.
It adds an is_available to Exchange and Forex to make it easier to determine if the exchange or forex can be used as the IPv4 feature flag was used to compile the canister or they support IPv6 out-of-the-box.
