[Feature Request] pwma support

[protoz]

I have an anycubic photon 4k that uses pwma file format. I'm not planning on setting up the serial connection at this point if it's even possible, but instead I want to use this as an over engineered wireless usb drive to reduce wear and tear on the usb connector.

When uploading, I am getting an unsupported file format type from the plugin. Is there much of a lift to support at least uploading the file type?
