Slip39

A minor release correcting the ability to produce the cover page.

An omitted .txt file prevented the app from saving the SLIP-39 cards. No other changes.

Most people do not have a Hardware Wallet that supports SLIP-39 natively, and many already have BIP-39 Seed Phrases and wallets that they do not want to change.

Backup your BIP-39 Seed Phrase to a set of SLIP-39 Mnemonic Card Groups. Once you test the Recover functionality, and confirm that you can securely and reliably recover your BIP-39 Seed Phrase whenever you wish, you can safely destroy your insecure and unreliable BIP-39 Seed Phrase backup(s).

Added coloration and simplified text to help the GUI flow better.

Beta support CRO and BNB (in Pro mode). Test that Paper Wallet accounts printed for CRO and BNB restore correctly before production use.

- Restored writing of PDF in `python -m slip39`, accidentally broken when printer support added.
- Enable Paper Wallet output in Windows .msi installer version of SLIP-39 App

Better installers for macOS and (especially) win32.

The macOS .dmg installer is code-signed, so should install without issues.

The win32 .msi installer is not (yet) code-signed, so you'll need to authorize it to run and install. A shortcut to the installed SLIP-39 executable is placed on the desktop.

For macOS, install the `SLIP-39-8.1.2.dmg`, and run `SLIP-39` from /Applications; for Windows, install the `slip39-8.1.2-win64.msi`, and run the `SLIP-39` shortcut on the Desktop.

On Linux, ensure you're running Python 3.9 (or later), run `python3 -m pip install slip39[gui,paper]`, and then run `slip39-gui` from the command-line.

App works on Windows and macOS

- Much simpler "Basic" controls by default, "Extra" and "Pro" selectable by radio-button
- Verified BIP-38 Paper Wallet encryption is correct
- Direct printing is available on macOS, in python -m slip39.gui and slip39-gui, but not yet in macOS App
