Remove numeric_casts from XML parsers
The code has been updated to use asserts where a sensible recovery path
was deemed impossible, and a conditional return for parse. In general,
our XML parsing will fail for any single parse of a document over
roughly 2 2GiB, which is probably not going to be a practical issue soon.
Test-Information:
Unit tests pass on macOS 10.13 using Expat and Debian 9 using LibXML
