b058bd310c Add support for RFC3164/RFC5424 formats 
Many devices send dates that do not conform to the RFCs...

Also add support for the strange "TZ-0700" variant of the "UTC-0700"
offset.

Cover all the changes with new tests.

d5b3c60e9b Cleanup handling of TZ name parsing 
Fully support the format where a TZ name is in parentheses after the
time (and possibly after an offset). This fixes the broken case where a
4 character TZ name was in parentheses after a time.

c4de5d4f6a Unify/fix timezone offset/name states 
* Merge duplicate states (fixes lots of edge cases)
* Support for +00:00 is consistent with +0000 now
* Support (timezone description) after any offset/name
* Update tests to cover positive/negative cases
* Update example with new supported formats

fd21b1ee3e Allow weekday prefix for most date formats 
This is implemented now using the "skip" parser field, indicating
to skip the first N characters. This also avoids a recursive parse
in one more case (more efficient). This simplifies the state machine
a little bit, while the rest of the code needs to properly account
for the value of the skip field.

Also allow whitespace prefix without penalty.

Modify the test suite to psuedo-randomly add a weekday prefix
to the formats that allow it (all except the purely numeric ones).

fbf07cc274 Optimize memory for error case 
New option SimpleErrorMessages that avoids allocation in the error path. It's off by default to preserve backwards compatibility.

Added benchmark BenchmarkBigParseAnyErrors that takes the big set of test cases, and injects errors to make them fail at pseudo-random places.

This optimization speeds up the error path runtime by 4x and reduces error path allocation bytes by 13x!

d2e1443c4d Comprehensive date format validation 
Audit every stateDate so every unexpected alternative will fail.

In the process, fixed some newly found bugs:
* Extend format yyyy-mon-dd to allow times to follow it. Also allow full month name.
* Allow full day name before month (e.g., Monday January 4th, 2017)

Relevant confirmatory test cases were added.

23f8fa1af0 Further optimize ambiguous parsing 
Optimize the common and special case where mm and dd are the same length, just swap in place. Avoids having to reparse the entire string.

For this case, it's about 30% faster and reduces allocations by about 15%.

This format is especially common, hence the reason to optimize for this case.

Also fix the case for ambiguous date/time in the mm:dd:yyyy format.

Fix for this bug mentioned in https://github.com/araddon/dateparse/pull/134

Also, the other cases mentioned in this PR are not valid formats, so add them to the TestParseErrors test, to document that this is expected.
