Doesn't function for blackpill stm32f401ccu6

Hi, I would like to ask why it show some error in library.

grpc: error while marshaling: string field contains invalid UTF-8

Compilation error: grpc: error while marshaling: string field contains invalid UTF-8

Start by reproducing the Blackpill STM32F401CCU6 compilation failure and inspect DHT.cpp at the reported lines 51, 112, and 158. Check how this Arduino library is expected to provide microsecondsToClockCycles and word for that target; done means the library compiles without these errors and the reported marshaling failure no longer occurs.
