Invalid escape sequence

**Describe the bug**
`configs.py` gives `SyntaxError: invalid escape sequence '\.'` from `IS_DEEQU_V1 = re.search("com\.amazon\.deequ\:deequ\:1.*", DEEQU_MAVEN_COORD) is not None`

Raw strings or double backslashes are needed.

**To Reproduce**
This only happens when running pytest and not from the REPL. I have not reproduced this independently yet. But dot and colon are not valid escape sequences.

**Expected behavior**
No errors from invalid escape sequences.

**Desktop (please complete the following information):**
macos running 6.10.0-linuxkit docker image.

**Additional context**
```
from pydeequ.configs import SPARK_VERSION
E File "/root/poetry/venv/lib/python3.10/site-packages/pydeequ/configs.py", line 43
E IS_DEEQU_V1 = re.search("com\.amazon\.deequ\:deequ\:1.*", DEEQU_MAVEN_COORD) is not None
E ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
E SyntaxError: invalid escape sequence '\.'
```

Öffne configs.py und überprüfe die reguläre Ausdruckszeichenkette um Zeile 43, wo die ungültigen Escape-Sequenzen gemeldet werden. Beginne damit, den pytest-Pfad auszuführen, der pydeequ.configs importiert, und verifiziere anschließend, dass der Import ohne den gemeldeten Escape-Fehler abgeschlossen wird.
