Keyboard k375s triple mode

Overview

The three-mode keyboard based on atmela's 32U4 wired module and Logitech K375S wireless module.
Logitech Unified's delay and power consumption are very well controlled, and the use of Unified's matrix can allow 32U4's limited IO to achieve 100 keys without collision, which
is best In conjunction with another open source project of mine, I combine USB2.0 HUB and Union charging, and can perform three-mode switching.
If there is a problem with the switch, Union will conflict with 32U4.
ldo can use 3v3
