Want to add 32 bit read/write functionality

[ModuloFS]

Hello,

i am using a Folinn H1 vfd and it supports 32 bit register values. This is simply possible by only writing and reading two registers with the write and read multiple registers function code 0x03 and 0x10.
I want to add this feature to your library and because of that i have a question. I cant find any documentation about your used modbus lib, so i am right that the number 1 in this function "modbus_read_registers(ctx, mconfig.rpmOut.address, 1, &value)" specifies the amount of read registers (same with the write function)?
How you have compiled your lib?
