Unable to install with pip3 install jsonschema2db

[Miro-Andrin]

I was trying to install this utility but got the following error. Just thought you might want to know.
I have tried doing this on my mac (homebrew) and now my linux desktop. My python version is 3.9.7,
and pip 21.0.1.

ERROR: Cannot install jsonschema2db==1.0.0 and jsonschema2db==1.0.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    jsonschema2db 1.0.1 depends on psycopg2==2.7.2
    jsonschema2db 1.0.0 depends on psycopg2==2.7.2

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

This looks like a problem with psycopg2, not jsonschema2db?

[cabljac]

I believe i got a similar issue, i think some package was renamed - the psycopg2 package was changed to psycopg2-binary

I created a PR with what i remember fixed it - #46

Will this be merged anytime soon?
