feat(renderer): Added hybrid-mode support to the plugin

Hybrid mode finally is complete & stable. You can set it up using the
new `hybrid_modes` option.

Example:

    modes = { "n", "i", "c" },
    hybrid_modes = { "i" },

Preview failure no longer crashes the plugin.

Renderer now has the following set of features,
  - Partial rendering of files(doesn't render things within a specific
    range)
  - Partial clearing. Now the renderer can clear only parts of the
    buffer.
  - Methods for finding node ranges. This is used to prevent nodes being
    unconcealed halfway.

Parser now has the following set of features,
  - Partial parsing. Only parses a specific range in the buffer.
