/**
* Creates a new Registry for mapping protobuf type identifiers/type URLs to
* actual implementations. Those implementations are typically generated with ts-proto
* but we also support protobuf.js as a type generator.
*
* By default, a `new Registry()` constains amost no types. `Coin` and `MsgSend` are in there
* for historic reasons but this does not make a lot of sense.
*
* There are currently two methods for adding new types:
* 1. Using the `register()` method
* 2. Passing custom types to the constructor.
* This only creates confusion for users. The reason here is historical.
* Using `register()` is recommended and 2. is deprecated because its behaviour
* will change in https://github.com/cosmos/cosmjs/issues/994.
*
* There is currently no way to unregister/override the default types. We should
* change the `customTypes` argument to override the default types if set.
* See https://github.com/cosmos/cosmjs/issues/994
