New update:
Tentative support for 8MB devices. Integrated bobtidey’s mods. Note that this has not been tested
on other than 2MB units at this time.
Added persistence and map modes, BMP load, and 30db extra gain to all FFT functions.
Updated spectrograph and XY modes + many minor improvements and bug fixes. See
changelog in README.TXT for complete list and how to use these. Program still fits
within 2 slots.

Persistence mode of RF eye pattern
