tlv: return parsed types from DecodeWithParsedTypes
This commit adds an additional return value to
Stream.DecodeWithParsedTypes, which returns the set of types that were
encountered during decoding. The set will contain all known types that
were decoded, as well as unknown odd types that were ignored.

The rationale for the return value (rather than an internal member) is
so that the stream remains stateless.

This return value can be used by callers during decoding to make
assertions as to whether specific types were included in the stream.
This is need, for example, when parsing onion payloads where certain
fields must be included/omitted depending on the hop type.

The original Decode method would incur the additional performance hit of
needing to track the parsed types, so we can selectively enable this
functionality when a decoder requires it by using a helper which
conditionally tracks the parsed types.

tlv: fix panic with large length
This commit fixes a panic where a large length in a record could
cause the DVarBytes function to fail to allocate a byte slice.
