To set up a REPL that has
cljs.core available, we need to re-partition the ESP32 and allocate more memory in Esprunio for "JsVars".
partitions_esprinuo.bin and rebuilt
espruino_esp32.bin are available here, followed by some description on how they are built in case you want to experiment for yourself.
partitions_espruino.bin gets flashed to
espruino_esp32.bin gets flashed to
0x10000 as per a usual ESP32 Espruino setup.
