fix(integer-basee-converter): handle prefix/suffix and case in sensitive

Handle common languages prefix : 0x, 0o, 0b (C/C#), &H, &O, &B (vb.net)
Handle common languages suffix : I (vb.net), U/L (C/C# unsigned and long), n (js bigint)
Handle case insensitive for base < 36 (ie, hexa) ( 36 = décimal + lower letters)
Fix CorentinTh#694
