Mangled values when input parameters have leading whitespace

[brryan]

Someone recently tried the input parameter block

<testblock>
 testparam = 2.0

and the result of GetReal("testblock", "testparam") was 0.0. This appeared to be due to Parthenon reading a value of = 2.0 and casting this string to a Real which resulted in 0.0. The problem was fixed by removing the leading whitespace from testparam. It appears we need to check parameter input for leading whitespace.

👍 presumably this is as easy as removing leading whitespace from every line when reading it in?

to quote @bprather (IIRC) "that's why you don't write your own parser" 😄

Linking #939 in case whoever fixes this wants to take a crack at some of those while they're in the parser code (or replacing it!)
