GHSA-mwcw-c2x4-8c55 Predictable results in nanoid generation when given non-integer values

• npm nanoid: >= 4.0.0, < 5.0.9 → fixed in 5.0.9 • npm nanoid: < 3.3.8 → fixed in 3.3.8

When nanoid is called with a fractional value, there were a number of undesirable effects: 1. in browser and non-secure, the code infinite loops on while (size--) 2. in node, the value of poolOffset becomes fractional, causing calls to nanoid to return zeroes until the pool is next filled 3. if the first call in node is a fractional argument, the initial buffer allocation fails with an error Version 3.3.8 and 5.0.9 are fixed.
