Added rate limit headers

Added additional rate limit data to API response headers. The following headers are now available to use when handling rate limiting programmatically:

• 'Retry-After': the number of seconds until the rate limit window resets
• 'X-RateLimit-Limit': the total number of requests allowed in the rate limit window
• 'X-RateLimit-Remaining': the number of requests remaining in the rate limit window
• 'X-RateLimit-Reset': the datetime when the rate limit window will reset
