Replacing pins.createBuffer() with control.createBuffer(), for RPi has not

[AqeeAqee]

Phenomenon:
When using this ext on hardware target RPi, would get following error

Cause:
RPi target has no createBuffer() in pins namespace.

Solution:
Relace it with control.createBuffer(). Functionality of both are the same, they all result in mkbuffer()

Target Version changed automatically in my commit, it's that OK? Or shall I re-submit a new one without pxt.json changed?

[pxt.json] "targetVersions": { ("target": "1.2.10",) "target": "1.8.22", "targetId": "arcade" },
