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%
