642ab409c1 Use Seek to speed up read/write in sysfs 
This maintains `direction` and `value` `File`s for each DigitalPin
implementation. Instead of Open/Read/Close we now only do Seek/Read,
this speeds up Read/Write operations a bit.

A silly benchmark on the mock FS gives:

benchmark                  old ns/op     new ns/op     delta
BenchmarkDigitalRead-8     647           7.36          -98.86%

benchmark                  old allocs     new allocs     delta
BenchmarkDigitalRead-8     5              0              -100.00%

benchmark                  old bytes     new bytes     delta
BenchmarkDigitalRead-8     96            0             -100.00%
