Ability to get raw byte length of Individual layers in vector tile

[khalilurrrahmanridoykhan]

Hi maintainers, I’m interested in working on this issue.

My proposed approach is to capture each layer message’s raw byte range while parsing the tile and expose its byte length as a read-only property on VectorTileLayer.

Before implementing it, could you confirm whether the expected value should include:

1. only the encoded layer-message payload, or
2. the complete encoded field, including the parent field tag and length prefix?

I would add focused parser tests, generated TypeScript declaration validation, and API documentation. I’m happy to follow your preferred property name and compatibility requirements.
