WIP: Normalized payload

[pablojimpas]

Summary

First steps for implementing #395

Changes

• Added uplinkNormalizer (similar to the previous uplinkDecoder)
• Started work on the new normalizedPayload schema, for now just with common quantities and sensor.

Notes for Reviewers

• This is just a work in progress draft, needs input and comments from all the interested parties.
• I'm not very familiar with JSON schemas nor the lorawan stack in general, so be aware.
• Some lines not relevant to this PR were reformatted by my editor, I did run npm run format but it didn't make a difference.

Release Notes

• Added the field normalizedPayload to standardize quantities and units, it is optionally created by the function uplinkNormalizer as an extra step in the decoding pipeline.
