/**
|
|
|
|
* Takes a user-authorable string with several whitespace delimited arguments and builds a byte array
|
|
|
|
* from it. Arguments can be hex data/numerals, decimal numbers or ASCII strings. Literals are padded
|
|
|
|
* to 32 bytes if prefixed by a '@' (or not prefixed at all), and tightly packed if prefixed by a '$'.
|
|
|
|
* Currency multipliers can be provided.
|
|
|
|
*
|
|
|
|
* Example:
|
|
|
|
* @code
|
|
|
|
* parseData("$42 0x42 $\"Hello\""); // == bytes(1, 0x2a) + bytes(31, 0) + bytes(1, 0x42) + asBytes("Hello");
