Introduce a short write HID command

[jose1711]

Majority (97 %) of my scripts fit under 30 bytes, many of them are around 10 bytes. Currently one needs to go through these steps in order to write a file:

• open a file for writing (0x0e)
• write data (0x0f)
• send close file command (0x10)

A new short_write command could be introduced which would be used for writing files under 58 bytes in a single HID command issued from a PC. The structure of the packet could be:

• PC to duckyPad:

Byte#	Description
0	0x05
1	Sequence number
2	0x??
3	profile index (0x01-0x10)
4	key index (0x1-0xf)
5 .. 62	data to write
63	0x00

• duckyPad to PC:

Byte#	Description
0	0x04
1	Sequence number
2	0 = SUCCESS, 1 = ERROR, 2 = BUSY
3 ... 63	0x00

This may result in improved performance when writing multiple smaller scripts.
