Parsing raw value from a field with leading or trailing 0's

DataSet parser trims leading and trailing 0s by default when the number is assigned to a field. For instance, here is the parser output of parsing 00013 and 13.131313000 

00013 and 13.131313000 
leadzero: 13 
message: 00013 and 13.131313000 
trailingzero: 13.131313

This results in the parsing field losing its raw message's value and affects the data accuracy 

As a result, we added a new parsing attribute to the parser engine to address the problem. By parsing the value as raw string, it prevents conversion to a number and changing its format. To use it, the attribute needs to be specified as $attributeName{parse=string}$

Using the same example from above, the parser definition would be like:

{ 
   formats: [
      {
         format: "$leadzero{parse=string}$ and $trailingzero{parse=string}$"
      }
   ]
}

It will produce the parsing output in its original format:

00013 and 13.131313000 
leadzero: 00013 
message: 00013 and 13.131313000 
trailingzero: 13.131313000
