RTCM parser library for Go

RTCM parser library implementation for Go

The biggest issue with this library is that it's not useful for constructing RTCM messages (only really for parsing them). It can be done, but realistically an abstraction would be required so that the developer experience isn't so painful and error prone.

An example of this is that masking is used to identify list lengths and satellite IDs in the RTCM binary structure. Meaning if you add a satellite to an MessageMsm7.SatelliteData, you also have to make a change to the satellite and signal masks. Ideally this would be abstracted such that the masks are computed during Serialization based on the data in the object.

A normalized Observation object may be useful for this. This would lead to scenarios like the following being easily implementable: input io provides a binary MSM7 1077 message which is deserialized into a normalized Observation struct, problematic satellites are removed, then the Observation is Serialized to output io as a binary MSM5 1075 message.
