Python, possibly others

A solution such as this one will sometimes pass the kata even though incorrect.

Tests should include years divisible by 100, especially in this case years that produce an odd number when floor div by 100.

See the fork just posted below for a fix for Python.

Python Fork

Includes fixed tests and random tests that are guaranteed to produce years that fail a "sometimes pass solution" such as this one.

There appears to be a problem with the Coffeescript version of this kata with respect to the Random Tests. I receive the following error message "RangeError: Maximum call stack size exceeded" when the Random Tests are performed. If I copy the first random test arguments and make a new Fixed test using those exact same arguments, the error message is not generated.

Deprecation warning in Rust (tests use an outdated function):

warning: use of deprecated associated function `chrono::NaiveDate::from_ymd`: use `from_ymd_opt()` instead
  --> src/lib.rs:54:36
   |
54 |         let mut first = NaiveDate::from_ymd(year, 1, 1);

C++ Translation.

Just realize i misunderstand the phrase the first in order of appearance

Example case: BAABB

If you think B is first in order of appearance, it's wrong.

A is correct answer. It can paraphrase 'the first in order of appearance which have highest length`

Rust: no random tests

Python new test framework should be used

JS: Should use Node v12 and the approriate assertion tools (mocha + chai).

Python new test framework should be used and 3.8 enabled
