feature: minimal human-readable serialization of uints

[prestwich]

Alternative to #225
Closes #224

Motivation

• Satisfy ethereum Quantity spec for uint serialization
  • strip leading 0 bytes
  • strip leading 0 nibbles
  • use 0x0 for the value 0
• Retain full-width serialization for bits
• Retain differentiation between human-readable and non-human-readable

Solution

• Modify serde support to include serialize_human_full serialize_human_minimal and serialize_binary
• use serialize_binary for non-human-readable serializers
• use serialize_human_full for bits in a human-readable serializer
• use serialize_human_minimal for uints in a human-readable serializer

This work is based on #225, but moves the functionality into differentiated methods, rather than a single method, and biases towards iterator usage

This PR is semver minor as the serialization output will change in a backwards-compatible way
