Represent HTTP only features in protobufs so they can be accessed by other connection methods.

This was suggested by @sachaw during the Meshtastic Dev Conference.

@sachaw I still don't totally understand this one

[sachaw]

Yeah, it's not named very clearly. What it's inferring is that http exclusive features. Range test CSV, file system browsing etc should be represented with protobufs so they can be accessed over any connection method.

add range test export over serial interface

triggered by a radioconfig enum, writes over serial using a delimited format with a defined header and footer.

I vote for a generic file send/receive over protobufs so we can provision devices by putting proto files into the flash filesystem. One use would be the oem.proto used for a secondary bootlogo and text.

Is this complete @caveman99?

The implementation is done, but there's room for improvement. I think we can close this.
