Number Parser: Refactor for improved algorithm

- Correctly handles prefix and suffix literals; #353;
- Loose Matching: This implementation is now much closer to UTS#35 7.1.2 Loose
  Matching http://unicode.org/reports/tr35/#Loose_Matching and fixes all
  reported cases that are related to it, including #288;
- Regression: Drop scientific notation parsing support, which wasn't documented
  anyway and shall be implemented by #533.

+// Loose matching for spaces [:Zs:].
+// 1: Uses regular space SPACE U+0020.
