In order to check the impact of this change in terms of performances, we compared previous implementation with the current one. Our performance snippet is: const {uniformIntDistribution,xoroshiro128plus} = require('pure-rand');
let g = xoroshiro128plus(42);
for (let idx = 0; idx !== NUM_TESTS; ++idx) {
g = lib.uniformIntDistribution(settings.min, settings.max, g)[1];
}Against: 2**16 - { min: 0, max: 0xffff })
2**32 - { min: 0, max: 0xffffffff }

Just in case it may explain perfs issues

Let's analyze where we spend most of the time into the merged code: Case A function() {
let g = prand.xoroshiro128plus(42);
for (let idx = 0; idx !== 1000000; ++idx) {
g = prand.uniformIntDistribution(0, 0xffffffff+1, g)[1];
}
}
Case B function() {
let g = prand.xoroshiro128plus(42);
for (let idx = 0; idx !== 1000000; ++idx) {
g = prand.uniformIntDistribution(Number.MIN_SAFE_INTEGER, Number.MAX_SAFE_INTEGER, g)[1];
}
}

Several different implementation of the feature have been tried:
Several benchmarks have been launched in an attempt to compute the cost of each of them compared to the current version of the code:
* Here 20% means:
#OperationsPerSecond(shared-arrays) / #OperationsPerSecond(master) = 0.8in other words master does 1.25 times more operations per seconds than shared-arrays.Test env details

One of the most important thing to keep in mind is that the initial code was not handling ranges larger than 232 properly thus even with such performance cost it is still better to fix the bug than letting it opened.
Fixes #63
