7e80f646b24a2abf3c031a649bcc706a695f80da Get the OutputType for a descriptor (Andrew Chow)
Pull request description:
Adds a `GetOutputType()` method to get the OutputType of a descriptor. Some descriptors don't have a determinate OutputType, so we actually use an `Optional<OutputType>`. For descriptors with indeterminate OutputType, we return `nullopt`.
`addr()` and `raw()` use OutputTypes as determined by the CTxDestination they have. For simplicity, `ScriptHash` destinations are `LEGACY` even though they could be `P2SH_SEGWIT`.
`combo()`, `pk()`, and `multi()` are `nullopt` as they either don't have an OutputType or they have multiple. `DescriptorImpl` defaults to `nullopt`.
`pkh()` is `LEGACY` as expected
`wpkh()` and `wsh()` are `BECH32` as expected.
`sh()` checks whether the sub-descriptor is `BECH32`. If so, it is `P2SH_SEGWIT`. Otherwise it is `LEGACY`.
The descriptor tests are updated to check the OutputType too.
