Allow Rate Limit Distinction Between Instruments #65
Description
Many of the OKX APIs allow for rate limits to be scoped not only by IP but also by instrument, for example the mark-price endpoint has a rate limit definition of:
Rate Limit: 10 requests per 2 seconds
Rate limit rule: IP + Instrument ID
It would be great if the rate limiting within the OKXRestClient was able to differentiate when different instruments are being requested.
