ols: use 32bit for handling sample counts

The OLS protocol sends 16bit values to specify the sample count and
delay count. However, this 16bit value is the number of 32bit words to
be sampled, so the actual sample count is 4 times larger and does not
fit into a uint16_t. Extend it to support the full range of 256K
(LogicShrimp will need this) and to prepare support for devices with
even more memory (Pepino).
