feat: Add read-only getters for Point.fields and Point.tags

[g3n35i5]

This makes testing easier.

Proposed Changes

I am currently contributing to a Jenkins Plugin which uses InfluxDB. Testing this plugin currently requires the use of Java reflections in order to compare written tags and fields.

Adding read-only getter functions for tags and fields would make this more easy.

@bednar I don't know what happened in the failed check ...

[bednar]

@g3n35i5, the client-backpressure check is flaky, so feel free to ignore it.

[g3n35i5]

@bednar any updated on this?

@g3n35i5 is is merged into master branch. How urgent is the release?

[g3n35i5]

Thanks! I just contributed this for better testability in other libraries, since there are workarounds it is not time critical.

Cheers!
