feat: add gzip support

[alespour]

Proposed Changes

• adds request body gzip compression controlled via payload content length (similarly to already existing support in Go and Javascript clients):
  • threshold and timestamp writing precision are now options in WriteOptions struct nested in InfluxDBClientConfigs - this is breaking API change!
• enables automatic response decompression

Checklist

• [x] CHANGELOG.md updated
• [x] Rebased/mergeable
• [x] A test has been added if appropriate
• [x] Tests pass
• [x] Commit messages are conventional
