Currently, each histogram range is hardcoded to
128 buckets (1ULL << 7), resulting in 58 ranges
(64 - 7 + 1) and a total size of 58 * 128 *
sizeof(uint64_t) = 59392 bytes.
To allow for more usage models in cases where this
size is prohibitive, enable the following changes:
1) specify number of buckets per range (in number of bits)
2) specify max datapoint value (in number of bits)
The latter can be useful for cases where datapoints
are never close to requiring all 64 bits - and allows
reducing the number of ranges. Any data points that
exceed the max will be tallied in the last bucket
in the last range.
Testing shows no performance disadvantage using the
dynamic approach.

The latency tracking is done with ranges of bucket arrays.
The bucket for any given I/O is determined solely by TSC
deltas - any translation to microseconds is only done after
the test is finished and statistics are printed.
Each range has a number of buckets determined by a
NUM_BUCKETS_PER_RANGE value which is currently set to 128.
The buckets in ranges 0 and 1 each map to one specific TSC
delta. The buckets in subsequent ranges each map to twice
as many TSC deltas as buckets in the previous range:
Range 0: 1 TSC each - 128 buckets cover deltas 0 to 127
Range 1: 1 TSC each - 128 buckets cover deltas 128 to 255
Range 2: 2 TSC each - 128 buckets cover deltas 256 to 511
Range 3: 4 TSC each - 128 buckets cover deltas 512 to 1023
Range 4: 8 TSC each - 128 buckets cover deltas 1024 to 2047
Range 5: 16 TSC each - 128 buckets cover deltas 2048 to 4095
etc.
While here, change some variable names and usage
messages to differentiate between the existing latency
tracking via vendor-specific NVMe log pages on Intel
NVMe SSDs, and the newly added latency tracking done
