internal/encoding/pack: initial commit

Package pack enables manual encoding and decoding of protobuf wire data.
This package is intended only for testing and debugging purposes.
Message.Marshal is useful for hand-crafting raw wire testdata in tests
in a readable form.
Message.Unmarshal is useful for parsing raw wire data for debugging.
For that reason, effort was put into trying to get its string formatted
output look humanly readable.

High-level API:
	type Number = wire.Number
		const MinValidNumber Number = wire.MinValidNumber ...
	type Type = wire.Type
		const VarintType Type = wire.VarintType ...

	type Token token
	type Tag struct { ... }
	type Bool bool
	type Varint int64
	type Svarint int64
	type Uvarint uint64
	type Int32 int32
	type Uint32 uint32
	type Float32 float32
	type Int64 int64
	type Uint64 uint64
	type Float64 float64
	type String string
	type Bytes []byte
	type LengthPrefix Message
	type Denormalized struct { ... }
	type Raw []byte

	type Message []Token
		func (Message) Size() int
		func (Message) Marshal() []byte
		func (*Message) Unmarshal(in []byte)
		func (*Message) UnmarshalDescriptor(in []byte, desc protoreflect.MessageDescriptor)
		func (Message) Format(s fmt.State, r rune)
