Avoid strtol on non-NUL-terminated input

...as could be observed with ASan and ASAN_OPTIONS=strict_string_checks=1 during
e.g. UITest_conditional_format.

strtol supports leading spaces, sign, and "0x", but none of that appears to be
relevant here, so readInt32 doesn't support that.

Hdf::m_pItData was redundant and always pointed at m_aItData.data(), and has
been elided to make it more obvious that the places that used it, which now also
need to use m_aItData.size(), actually use m_aItData.
