mtools[mlaunch] does not install with pymongo 4

[p-mongo]

Expected behavior

I think mtools and mtools[mlaunch] should have the same acceptable dependency versions?

Actual/current behavior

I can install mtools+pymongo 4.1:

serene2% pip install mtools==1.7 pymongo==4.1

However if I request mtools[mlaunch] + pymongo 4.1 I get an error:

serene2% pip install mtools'[mlaunch]'==1.7 pymongo==4.1
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: mtools[mlaunch]==1.7 in /home/w/.local/lib/python3.9/site-packages (1.7.0)

ERROR: Cannot install mtools[mlaunch]==1.7.0 and pymongo==4.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested pymongo==4.1
    mtools[mlaunch] 1.7.0 depends on pymongo<4.0.0 and >=3.12.2; extra == "mlaunch"

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Steps to reproduce the actual/current behavior

Thanks @p-mongo - dependency versions should be the same but setup.py is out of sync with requirements.txt in 1.7.0.

It should allow pymongo>=3.12.2,<5.0.0.
