Remove all ANSI codes from buf

[denisbondar]

Description

As discussed in the discussion #301, these regular expression modifications allow all possible combinations of ANSI codes to be removed from the buffer probably.

Type of change

Please delete options that are not relevant.

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

The following unit test was augmented with two parameters:

@pytest.mark.parametrize(
    "buf, expected",
    (
        (
            b"[[email protected]: \x1b[1m/\x1b[0;0m]$",
            b"[[email protected]: /]$",
        ),
        (
            b"VeryLong\x1bECommand",
            b"VeryLongCommand",
        ),
        (
            b"command-prompt# \x1b7",
            b"command-prompt# ",
        ),
        (
            b"\x1b[7mCTRL+C\x1b[0m \x1b[7mESC\x1b[0m \x1b[7mq\x1b[0m Quit \x1b[7mSPACE\x1b[0m \x1b[7mn\x1b[0m Next Page \x1b[7mENTER\x1b[0m Next Entry \x1b[7ma\x1b[0m All\x1b[1A\x1b[59C\x1b[27m",
            b"CTRL+C ESC q Quit SPACE n Next Page ENTER Next Entry a All",
        ),
    ),
)
def test_strip_ansi(base_channel, buf: bytes, expected: bytes):
    actual_strip_ansi_output = base_channel._strip_ansi(buf=buf)
    assert actual_strip_ansi_output == expected

Regarding the successful execution of all unit tests, some tests that depend on the presence of an SSH server on the host failed as expected. I mean tests using socket_transport. I also wrote about it in the discussion #301.
