blurhash panics on parsing crafted inputs

The blurhash parsing code may panic due to multiple panic-guarded out-of-bounds accesses on untrusted input.

In a typical deployment, this may get triggered by feeding a maliciously crafted blurhashes over the network. These may include:

Patches

The patches will be released under version 0.2.0, which requires user intervention because of slight API churn.
