/************************* WARNING ***********************
Due to the way extensions are accessed in pb2py, there needs to be a globally unique
name-ID mapping for extensions. That means that two different extensions, e.g. for
EnumValueOptions and FieldOptions, MUST NOT have the same ID.

Using the same ID indicates the same purpose (protobuf does not allow multiple
extensions with the same name), such as EnumValueOptions.bitcoin_only and
MessageOptions.include_in_bitcoin_only. pb2py can then find the extension under
either name.

The convention to achieve this is as follows:
 - extensions specific to a type have the same prefix:
   * 50xxx for EnumValueOptions
   * 51xxx for EnumOptions
   * 52xxx for MessageOptions
   * 53xxx for FieldOptions
 - extensions that might be used across types have the same "global" prefix 60xxx
