Commit Message

Introduce UnmarshalEnvelopeLite to speed up mapBlock (#316)

#### Type of change

- Improvement (improvement to code, performance, etc)
 
#### Description

Replace full proto.Unmarshal of Envelope→Payload→ChannelHeader (3
chained
deserializations) with direct protobuf wire-format scanning that
extracts
  only the needed fields (HeaderType, TxID, Data). This reduces envelope
parsing from 287 ns/op to 72 ns/op — a 4x speedup with 7 fewer
allocations.

  BenchmarkUnwrapEnvelopeLite-14   16929306     71.5 ns/op    72 B/op   2 allocs/op

```
With UnmarshalEnvelopeLite, the new mapBlock is able to process 1.7x
more blocks.
