[new release] uuseg (15.1.0+dune) (#209)

CHANGES:

- Unicode 15.1.0 support.
- Requires OCaml 4.14.0 for the UTF decoders.
- The `Uuseg_string` module was rewritten to use the standard library
  UTF decoders and was moved to the `uuseg` library. The `uuseg.string`
  library is deprecated, it warns on usage and simply requires `uuseg`.
- The sample code was rewritten to use the standard library UTF
  decoders.

+synopsis: "Unicode text segmentation for OCaml"
+description: """\
+Uuseg is an OCaml library for segmenting Unicode text. It implements
+the locale independent [Unicode text segmentation algorithms][1] to
+detect grapheme cluster, word and sentence boundaries and the [Unicode
+line breaking algorithm][2] to detect line break opportunities.
+
+The library is independent from any IO mechanism or Unicode text data
+structure and it can process text without a complete in-memory
+representation.
+
+Uuseg is distributed under the ISC license. It depends on [Uucp].
