initial implementation (#1)

* initial implementation

* address a couple review comments

* use "Infinite Athlete, Inc." everywhere
* get rid of unneeded `Cargo.toml` release profile tweaking

* delete stray extra file

* address some review feedback

* add `Frame`/`FrameBuf` abstraction to allow caller to avoid
  preinitialization without any use of `unsafe`. This also offers
  an interface for padded lines, although the conversion currently
  returns unsupported if it's used.

* return a `ConversionError` rather than the more specific
  `Unsupported`. The error is currently opaque; this could be changed
  later without breaking compatibility.

* fix x86_64 compile error

* remove obsolete MaybeUninit import line

* overhaul `Frame` design

* clippy

* fix bench crash

* add plane ref/mut constructors; tiny fixes

* fix obsolete comment

* consistently panic as advertised in `PartialEq`

* re-export entire `arrayvec` crate
