Constructors of ALL types should be immune to whitespace characters - whitespace characters should be omitted. Sample below

Input:
integer(" 6789 ") eq integer(" 6789 ")

Output:
⚠️ ️There was an error.

Code: [XPTY0004] (this code can be looked up in the documentation and specifications).

Location information: file:/Users/mstevan/Documents/:LINE:1:COLUMN:0:

6789 : value of type string is not castable to type integer.

Expected output:
true

All tests are passing. At the moment, there are no other tests crashing because of fix
