I've got some ESP-01's here that I'd like to put esprunio on they're a 1MB board according to esptool:
```
esptool.py v3.3-dev
Serial port /dev/tty.usbserial-220
Connecting....
Detecting chip type... Unsupported detection protocol, switching and trying again...
Connecting...
Detecting chip type... ESP8266
Chip is ESP8266EX
Features: WiFi
Crystal is 26MHz
MAC: a4:cf:12:c9:1f:ab
Uploading stub...
Running stub...
Stub running...
Manufacturer: 5e
Device: 4014
Detected flash size: 1MB
Hard resetting via RTS pin...
```
Can someone advise on the command I'd need to flash them with and if I can use files from the published builds, (I don't really want to get into setting up a build environment for these) Can I use (some of ) the files in https://www.espruino.com/binaries/espruino_2v11_esp8266_4mb/ with a different map?
