Adds varint encoding to all numbers, including sequence lengths and enum discriminants. Varints are encoded according to the following scheme
1. If `u < 251`, encode it as a single byte with that value.
2. If `251 <= u < 2**16`, encode it as a literal byte 251, followed by a u16 with value `u`.
3. If `2**16 <= u < 2**32`, encode it as a literal byte 252, followed by a u32 with value `u`.
4. If `2**32 <= u < 2**64`, encode it as a literal byte 253, followed by a u64 with value `u`.
5. If `2**64 <= u < 2**128`, encode it as a literal byte 254, followed by a u128 with value `u`.
Signed integers are first encoded using zigzag format (see docs for details)

Deprecate the old config system and make a refined version of the internal config system public. Doing allows the Serializer/Deserializer to be exposed since all of its generic type parameters are now public.
* add option and config traits
* thread options everywhere
* add WithOtherLimit, WithOtherEndian, and update internal to take advantage of it
* wip
* add rest of the public API and fix tests
* dtolnay feedback
* remove serialized_size_bounded and replace it with a use of config
* remove inline from trait method
* finish documentation and add custom reader support
* minor config_map refactor
* doc changes
* add with_(de)serializer functions and their associated modules
... by utilizing that bincode is not human readable.
Uses the changes in https://github.com/serde-rs/serde/pull/1044 which
allows data formats to report that they are not human readable. This
lets certain types serialize themselves into a more compact form as they
know that the serialized form does not need to be readable.
Closes#215
BREAKING CHANGE
This changes how types serialize themselves if they detect the
`is_human_readable` state.
