1. Improve destructuring and re-implement in pcase. …

   # Basic Changes
   
   - Update README and CHANGELOG.
   - Add destructuring features
   - Re-implement destructuring using `pcase`.
   
   # More Details
   
   ## All Constructs
   
   - Re-implement destructuring of normal values using `pcase`, reducing the
     maintenance burden and making further improvements easier.
     - Make it so that the existing destructuring features will signal
       an error if the `pcase` pattern doesn't match, instead of failing silently
       as in `pcase`.
   - Support full forms being vectors as well as lists.
   
   ## `&key`
   
   - Improve `&key`:
     - Make `&key` signal an error when there are unmatched keys in the property
       list.
     - Add `&allow-other-keys`.
     - Support the full form `((KEY VAR) DEFAULT SUPPLIED)`.
   
   ## `&map`
   
   - Add `&map` as `(KEY VAR DEFAULT SUPPLIED)`.
   
   - Add `&optional` form `(VAR DEFAULT SUPPLIED)`.
   - Rename `loopy--parse-destructuring-accumulation-command`
     to `loopy--parse-destructuring-accumulation-command-default`
   - Remove alias `loopy--destructure-generalized-variables`
     from `loopy--destructure-generalized-sequence`
   
   ## New Files
   
   - Move some destructuring features from `loopy-misc.el` to
     `loopy-destructure.el`.
   - Move some instruction features from `loopy-misc.el` to
     `loopy-instr.el`
   
   ## Test Changes
   
   - Add many tests.
   - Update the `Makefile`.
   - Only test the most recent minor version of each major version.
   
   ## Removed Features
   
   - Remove the following functions:
     - `loopy--every-other`
     - `loopy--split-list-before`
     - `loopy--split-off-last-var`
     - `loopy--destructure-sequence`
     - `loopy--destructure-list`
     - `loopy--destructure-array`
     - `loopy--generate-inc-idx-instructions`

     - `loopy--get-var-groups`
     - `loopy--get-&key-spec`
