Points to the specific PR merge that included the libsecp256k1 binary compiled for the Pi Zero (armv6l).

Compiled binary speeds up basic ECDSA math by roughly 8.5k, depending on the task.

Updates SeedSigner to embit v0.4.14.

Further considerations:

• In initial tests with simple PSBTs, signing a PSBT is now nearly instantaneous. If signing more complex PSBTs are reasonably fast, it may make sense to remove the loading/waiting spinner on that page.
• Similarly, brute-force address verification is so fast that "Skip 10" now seems pointlessly small. Perhaps a "Skip 50" or "Skip 100"?
