Pad Zero v0.3.0

Maintenance release. If v0.2.0 works for you, there is no need to update.

What's new

• Clearer message when the USB connection drops. If the printer stops responding mid-reset (almost always a stuck USB connection, not a fault), the window now tells you to unplug the cable and try again, instead of showing a confusing internal error. Reported by an L120 user whose reset worked after a restart.
• New tool for unlisted models: find_key_usb.exe. If your printer isn't in the list yet, this searches for the key it needs over USB. It is read-only and never changes anything. If it finds a key, open an issue with the result and the model can be added for everyone.

Reminder

This resets the counter. It does not empty the pads. If the pads are full, put something absorbent under the printer and fit a replacement pad or waste tank. AGPL-3.0-or-later. Not affiliated with Seiko Epson Corporation.
