Fix repeat frames

[LandryNorris]

Frames previously were not properly repeating. This PR should fix that. Tested with the following js program

CanBridge.sendCANMessage(descriptor, 0xCBA321, [0x12, 0x34, 0x56, 0x78], 150)

await new Promise((resolve) => setTimeout(resolve, 2000));

CanBridge.sendCANMessage(descriptor, 0xCBA321, [0x34, 0x56, 0x78, 0x12], 150)

await new Promise((resolve) => setTimeout(resolve, 2000));

CanBridge.sendCANMessage(descriptor, 0xCBA321, [0x34, 0x56, 0x78, 0x12], 100)

await new Promise((resolve) => setTimeout(resolve, 2000));
