v0.1001.0

Breaking changes

• Changed the name of the detailed-errors feature to have a hyphen instead of
  an underscore, consistent with the other feature names.
• Renamed the vecblob encoder to plainbytes.
• Encoded bilrost values and semantics no longer rely on the Default
  implementation for their empty values.
  • Message no longer requires, nor does its derive macro provide, an
    implementation of Default.
  • Enumeration no longer cares whether the type has a Default
    implementation, only whether there is a variant whose Bilrost value is
    exactly 0.
  • All of the above duties are taken on by the HasEmptyState trait, as does
    the base implementation for NewForOverwrite.
• Following on that, renamed the HasEmptyState trait to EmptyState.
• Usability fixes for Blob: new(..) has been changed to create an empty
  Blob with no arguments, and the functionality for wrapping a vec has been
  renamed to from_vec(..).
• Added APIs for replace_from(..) etc. to the regular non-dyn Message
  traits, which is useful for messages with ignored fields but requires those
  same APIs in the MessageDyn and DistinguishedMessageDyn traits to be
  renamed to replace_from_dyn(..) etc.

New features

• Added features that enable support of smallvec, thin-vec, and tinyvec.
• Added support for u16 and i16 with the general encoder, and added a
  new varint encoder that supports all the varint types in addition to u8
  and i8. general will not support one-byte integers, because this makes it
  too easy to accidentally spell a completely unintended encoding of Vec<u8>;
  encodings for collections of bytes like this will remain explicit.
• Added support for [u8; N] with the plainbytes encoder, which only accepts
  values of the correct length.
• Added support for [u8; 4] and [u8; 8] with the fixed encoder.
• Added support for marking message fields with #[bilrost(ignore)], which
  causes the field to be excluded from encoding and decoding but precludes
  distinguished decoding.
• Added replace_from_slice(&[u8])
  and replace_distinguished_from_slice(&[u8]) to the MessageDyn
  and DistinguishedMessageDyn traits.
• Changed value-decoding to pass down whether or not an empty value is allowed,
  allowing implementations to err sooner and cheaper by detecting that the
  encoded data is that which represents the empty value, rather than always
  checking the value for emptiness after the fact.

Fixes

• Require the serde_json/float_roundtrip feature for
  the bilrost-types/serde_json compatibility. If that feature is desired to be
  disabled, the serde_json feature in bilrost-types currently only provides
  from/into anyway and those can be written elsewhere.

Cleanups

• Deduplicated implementations of Encoder and DistinguishedEncoder that
  blanket all implementations for which those encoders support value-encoding.
• Great strides in expanding and cleaning up the documentation.
