v0.4.0

Add a converter command line application and fix a few slow conversion issues and some other fuzz issues that came up recently, add isnormal operation for measurements, better test coverage for fixed_precise_measurement, some additional tests and static analysis checks.

Changed

• Added several tests run under Azure to remove deprecated image and add some new tests #40
• clears up several warnings from clang-tidy #41
• the fuzzer now uses fuzz_measurement #42
• update clang format to limit line length to 80 and allow reflowing comments #43
• add clang-tidy checks for the tests and fix a few issues. #47

Fixed

• A few timeouts on the fuzzer- the fix was to generalize the multiplier insertion after ^ to accept multiple digits after the ^ instead of just ignoring it after more than one. #34
• An asymmetry was observed in the unit equality from on the fuzzers, this resulted in some modifications of the cround_equal and cround_precice_equals functions. Also noted that the functions weren't aborting on exact floating point equality so were doing quite a bit of extra calculations. #34
• A timeout issue from fuzzing having to do with not injecting multiplies after [] in some circumstances. The fix was to be a little more refined as to which point to not inject the * and to do it in multiple stages so as to not rely on the partitioner so much. #35
• fixed_measurement and fixed_precise_measurement had incorrect subtraction operation in a few overloads. #39
• fixed a few initial issues from fuzz_measurement #42
• Some more fuzzing generated issues with cascading powers #45
• A number of additional clang-tidy checks were added and the resulting warnings fixed #46
• An issue from the fuzzer dealing with equation type units #51
