nv-string-s2n
=======================
- parse a string to a number, same as eval("1.1....")

- support 0b|0B  0o|0O  0x|0X , bigInt,  double, NaN , Infinity , -Infinity  JUST Like  parseFloat DO;
- support lodash _ seperator, loose rule, NOT so strict as parseFloat;

- extra  support  0q|0Q,   it means radix 4

- NOT support  oct-using-leading-0-without-oO, such as 034
- IF meet BigDemical, it do NOTHING  just return a pair ["maybe\_big\_demical",\<the-original-string\>]


- this pkg is SLOW(
         50 times slower than parseFloat/parseInt/Number/BigInt
   ) , should ONLY  be used in repl/cli TOOLS , its just for test the state-transfer when parseFloat. 

- but its faster than eval


- it is USED for test  0q123 0Q123  in nvlang,   nvlang support int-number-literal-of-radix-4
