This release:

• implements support for the TRNG of the RP2350, to replace the use of RANDOMBIT on it. This provides significantly higher-quality random numbers than before. Note though that this is slow, and rng::random should not be used directly for generating arbitrary numbers, but rather is useful for seeding a PRNG such as TinyMT32 (which is included with zeptoforth).
• adds a build script, utils/build_picocalc_zeptoip.sh, for building zeptoforth on the PicoCalc with zeptoIP and the CYW43439 driver included. Note that the CYW43439 firmware is not in the zeptoforth repository for licensing reasons.
• adds an optional I2C CH1116 display driver.
• adds an optional NTC thermistor driver.
• adds support for reverse text and selecting default foreground and background colors in ansi-term.
• fixes a bug shared between extra/rp_common/picocalc_screenshot.fs and extra/rp_common/picocalc_screenshot_text.fs where they would not compile on the RP2040.
• fixes a bug in the text-only PicoCalc terminal emulator where the last line of each character would not be rendered properly.
