Alternative way to install os-specific dependencies

[Riccardo Briccola]

I found this example to install os-specific dependencies (specifying it in pyproject.toml) which seems better that having user to specify the os in the pip install command.

Source

[project]
dependencies = [
  'cached-property >= 1.2.0, < 2',
  'distro >= 1.5.0, < 2',
  'docker[ssh] >= 4.2.2, < 5',
  'dockerpty >= 0.4.1, < 1',

  # Conditional
  'backports.shutil_get_terminal_size == 1.0.0; python_version < "3.3"',
  'backports.ssl_match_hostname >= 3.5, < 4; python_version < "3.5"',
  'colorama >= 0.4, < 1; sys_platform == "win32"',
  'enum34 >= 1.0.4, < 2; python_version < "3.4"',
  'ipaddress >= 1.0.16, < 2; python_version < "3.3"',
  'subprocess32 >= 3.5.4, < 4; python_version < "3.2"',
]

As you can see, there's a sys_platform condition. What do you think @infeeeee ?

Nice! Much better solution!
