`String.random(options = { ... })` _(ext/string/random)_

Returns generated random string, contained only of ascii cars `a-z` and `0-1`. By default returns string of length `10`.

const random = require("ext/string/random");
random(); // "upcfns0i4t"
random({ length: 3 }); // "5tw"

# Supported options:

## <tt>isUnique: false</tt>

Ensures generated string is unique among ones already returned.

Note: When not applying this setting, accidental generation of same string is still highly unlikely. Provided option is just to provide a mean to eliminate possibility of an edge case of duplicate string being returned

## <tt>length: 10</tt>

Desired length of result string

## <tt>charset: null</tt>

Fixed list of possible characters

random({ charset: "abc" }); // "bacbccbbac"
