[new release] yojson and yojson-bench (2.0.0)

CHANGES:

### Removed

- Removed dependency on easy-format and removed `pretty_format` from
  `Yojson`, `Yojson.Basic`, `Yojson.Safe` and `Yojson.Raw`. (@c-cube, ocaml-community/yojson#90)
- Removed dependency on `biniou`, simplifying the chain of dependencies. This
  changes some APIs:
  * `Bi_outbuf.t` in signatures is replaced with `Buffer.t`
  * `to_outbuf` becomes `to_buffer` and `stream_to_outbuf` becomes
    `stream_to_buffer`
  (@Leonidas-from-XIV, ocaml-community/yojson#74, and @gasche, ocaml-community/yojson#132)
- Removed `yojson-biniou` library
- Removed deprecated `json` type aliasing type `t` which has been available
  since 1.6.0 (@Leonidas-from-XIV, ocaml-community/yojson#100).
- Removed `json_max` type (@Leonidas-from-XIV, ocaml-community/yojson#103)
- Removed constraint that the "root" value being rendered (via either
  `pretty_print` or `to_string`) must be an object or array. (@cemerick, ocaml-community/yojson#121)
- Removed `validate_json` as it only made sense if the type was called `json`.
  (@Leonidas-from-XIV, ocaml-community/yojson#137)

### Add

- Add an opam package `yojson-bench` to deal with benchmarks dependency
  (@tmcgilchrist, ocaml-community/yojson#117)
- Add a benchmark to judge the respective performance of providing a buffer vs
  letting Yojson create an internal (ocaml-community/yojson#134, @Leonidas-from-XIV)
- Add an optional `suf` keyword argument was added to functions that write
  serialized JSON, thus allowing NDJSON output. Most functions default to not
  adding any suffix except for `to_file` (ocaml-community/yojson#124, @panglesd) and functions
  writing sequences of values where the default is `\n` (ocaml-community/yojson#135,
  @Leonidas-from-XIV)

### Change

- The `stream_from_*` and `stream_to_*` functions now use a `Seq.t` instead of a
  `Stream.t`, and they are renamed into `seq_from_*` and `seq_to_*` (@gasche, ocaml-community/yojson#131).

### Fix

- Avoid copying unnecessarily large amounts of strings when parsing (ocaml-community/yojson#85, ocaml-community/yojson#108,
  @Leonidas-from-XIV)
- Fix `stream_to_file` (ocaml-community/yojson#133, @tcoopman and @gasche)
