Nestjs does not transform dates

[alexvallecit]

When using the --ts_proto_opt=nestJs=true option it does not create the functionality to switch from Timestamp to Date.

Hi @alexvallecit ; yeah, you're right; this is a known issue with the NestJS infra and is discussed in #69.

Note that #69 has been open for awhile, but ~a month ago someone did finally figure out how to tell the protobufjs runtime to use ts-proto's custom encode/decode methods for things like dates, but unfortunately that insight has not been turned into a PR that works for all types yet.

If you're interesting in helping fix that, check that issue out.

Thanks!
