applet.radio.nrf24l01: add ShockBurst support. Very useful for raw GMSK RX/TX.

applet.radio.nrf24l01: flush applet FIFO before pulsing CE. We really need to get the SERDES+sideband design working.

applet.debug.mips: don't reset PrAcc bit by accident. This was broken in 1b830bc3, and caused most PrAcc instrutions to be skipped.

protocol.gdb_remote: fix type error. Introduced in 3aed7c41.

applet.memory.24x: allow binary literals as -A arguments.

applet.audio.yamaha_opx: fix outdated help text.

applet.audio.yamaha_opx: relax timeout. The current value is way too aggressive and leads to spurious timeouts in some conditions. The only purpose of this timeout is to guard against a hung undervolted chip, so the exact value is not very important, only that it's not too long.

applet.interface.jtag_probe: fix typo.

revC1: fix formatting issue in BOM. Line 21 was missing several columns.

applet.interface.jtag_probe: add missing help messages. To be more like run-repl.
