initial commit: fork of yorickpeterse/nvim-jump

Fork of https://github.com/yorickpeterse/nvim-jump (MPL-2.0) with one
addition: `label` accepts a table of nvim_set_hl attributes in
addition to a group name, and the plugin re-applies it on ColorScheme.

Upstream declined the feature as out of scope (the project is
considered feature-complete), so it lives here instead. Credit for the
core implementation goes to Yorick Peterse.

Changes relative to upstream:
- Module renamed 'jump' -> 'tiny-jump'
- Namespace and augroup renamed accordingly
- Internal managed highlight group renamed 'JumpLabel' -> 'TinyJumpLabel'
- Default `label` changed from 'FlashLabel' to 'IncSearch' (no longer
  catering to flash.nvim migration)
- README rewritten
