CH347T-V1.0

Fast USB chip programmer CH347T V1.0.
Supports 24xxx, 25xxx, 93xxx series chips.
This programmer uses Nanjing Qinheng Microelectronics CH347T chip, which allowed to increase the speed of reading and writing chips several times in comparison with the programmer using CH341A chip. The /HOLD signal is still connected to the 3.3V supply. The /WP signal is left unconnected.  This is incorrect. These signals should be connected to the 3.3V supply via 4K7 resistors. This should be corrected in the future. There is no point in the UART (H2) connector, as the chip mode switching is not brought out on switches or jumpers.
