Normalise

Check systems are not validating if the input is within the expected values, if required, the following function are provided:

iso7064.NormaliseNumeric("1A3 4")

iso7064.NormaliseAlphabetic("aB1c")
// output: "ABC"

iso7064.NormaliseAlphaNumeric("aB1 c")
// output: "AB1C"

Pure systems:

Designation	Input (string)	Output (string)
MOD 11-2	numeric	1 digit or X
MOD 37-2	alpha numeric	1 digit or letter or *
MOD 97-10	numeric	2 digits
MOD 661-26	alphabetic	2 letters
MOD 1271-36	alpha numeric	2 digits or letters

Hybrid systems:

Designation	Input (string)	Output (string)
MOD 11,10	numeric	1 digit
MOD 27,26	alphabetic	1 letter
MOD 37,36	alpha numeric	1 digit or letter
