Switch Payload Loader v1.5

This is moderately tested. Although no issues have been discovered, I'm not responsible if anything goes wrong!

Warning: It seems like some update to WebUSB might have broken this implementation.

This may or may not work on Windows due to a limitation in the Chrome implementation of WebUSB (and probably other reasons!). In my testing, it will sometimes work so give it a shot, but be wary.

This does NOT currently work on any browser but Chrome, because they don't implement WebUSB.

On Linux, you might get an 'Access Denied' or 'No Compatible Device' error on the Connect dialog! If you do, you can try creating a file at /etc/udev/rules.d/50-switch.rulesWith the following contents:
SUBSYSTEM==\"usb\", ATTR{idVendor}==\"0955\", MODE=\"0664\", GROUP=\"plugdev\"

This has been tested and appears to work on Linux, OSX, Android (unrooted) and Chromebooks. Your mileage may vary.

Instructions:

Put the Switch in RCM, and connect it to your device.
Select either the example payload, or upload one.
Press 'Deliver Payload!'
On the consent screen that appears, select 'APX' and hit 'Connect'.
If all goes well, the payload will launch!
