.clang-tidy typo

[NicksWorld]

.clang-tidy contains a typo which causes the readability suite of tests to remain disabled. Changing this line to read readability-* will enable these lints. A quick test with clang-tidy enabled emits a number of new warnings.

The lints include a number of warnings on items that may be deemed unnecessary such as requiring the integer suffixes to be uppercase, which may warrant being disabled as well.
