Need Methodology for Saving Small Animated QRs as Static QRs

Currently, GST displays some QRs that _could_ be displayed as static QRs as animated QRs. For example:
https://github.com/BlockchainCommons/crypto-commons/blob/master/Docs/crypto-seed-test-vectors.md#seed-with-date-name--long-note

There is currently no way to save or share these QRs.

A minimum methodology would be:

If a QR is large enough that it is animated in GST, but not large enough to _require_ that animation.

* Then, on long-touch of QR, save or share it as a static QR.

If a QR is large enough that it is animated in GST, *and* large enough to _require_ that animation.

* For now, display an error screen that says, "Sorry, this QR code is too large to be displayed as a static QR; please export via another method".
* Long term, decide on a methodology to export an animated QR as an animated GIF.
