hw: update resistors R20-R23 value in parts_SMT.xlsx

hw: fix jst connectors drill (motor connectors) and pad size (iServo connectors), move bottom pinheads to left to make enough space for iServo connectors

hw: disconnect 3V3_EN and D11 (this connection prevents main step-down IM1 from startup)

hw: change resistors R20 - R23 valu to 2k2 (VUSB and ESP_+5V power LED resistors)

hw: change version to v1.2

Merge pull request #50 from RoboticsBrno/vel-ramp Vel ramp

Use sqrti

Smoothen regulation enable transition, increase acceleration

Use better ramping logic

Merge pull request #44 from RoboticsBrno/motor-posreg Add motor position regulation
