Running

pip install codecov
codecov

on Semaphore CI fails with the following error:

Traceback (most recent call last):

  | File "/home/semaphore/.pyenv/3.7/bin/codecov", line 8, in <module>
  | sys.exit(main())
  | File "/home/semaphore/.pyenv/3.7/lib/python3.7/site-packages/codecov/__init__.py", line 365, in main

  | TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'
  | exit code: 1 duration: 0s

This is to be expected as SEMAPHORE_BUILD_NUMBER is not listed in the docs. This seems to be a difference between Semaphore 2.0 and Semaphore, where this env var is available.

Is there support for Semaphore 2.0?
