Redundant commands in ProgramPage

[ccrause]

https://github.com/dcwbrown/dwire-debug/blob/d6af573913dd030b492ef3ae7d56bfd1f9226b65/src/commands/NonVolatile.c#L141

There is no need for DwSend(Bytes(0x66)) before calling DwSetRegs since DwSetRegs sends the appropriate setup command.

Similarly DwSend(Bytes(0x64)) on line 144 is also redundant since the following DwOut call sends this via DwInst.
