fix: remove Record word conflict

[stezu]

When a protobuf file contains a message named Record, it causes conflicts with the utility types at the bottom of the file which were using the built-in TS Record utility. This obviously causes the file to contain invalid Typescript since we'd expect Record to be the utility generic, not the non-generic type generated by this library.

To alleviate this issue, I added a test to treat Record as a reserved word and fixed the implementation to avoid using it and instead used the mapped types to emulate what Record does. The alternatives I considered seemed to be more trouble than they were worth given that there was only the single usage of Record in the generated output.

@stezu this looks good!

Can you run yarn proto2bin to re-create the *.bin files? In theory none of those should have changed, and the proto2bin script will use docker to make sure any host-dependent / protoc-version-dependent changes are not included in the *.bin files.

@stephenh I was wondering about that, thanks for the tip!

Looks great, @stezu , and thanks for the regression test on Record!
