blob: better binary

blob brings binary to your shortcuts.

- blob encoding!
a base256 format that makes data distinct and type safe.

- other formats!
supports binary, hex, decimal, base32, base64, and xxd data.
and UTF-8, and ascii text.

- type safety!
blob actions use consistent parameter and return value labels
to ensure you're using what you want, where you want it.

- no more encoding blunders!
each action either performs text -> data or data -> text,
so you never end up encoding your encoded string,
or interpreting encoded data as text.

- keep track!
the app records every action to view, share, and debug.

- additional tools!
Substring and Random Bytes because they're helpful.
