alsaseq constants have wrong values

[Alice Heaton]

Ubuntu 20.04.2 LTS
python3-pyalsa 1.1.6-2build2
Python 3.8.5
Linux kernel 5.4.0-66-generic
Arch x86_64

When I install python3-pyalsa I get the following:

>>> from pyalsa import alsaseq
>>> int(alsaseq.SEQ_EVENT_NOTE)
1329268363771656936786755287825360689

This is not the correct value !

If I install pyalsa as a Python package (dircectly from the Github repo), I get the correct value (this is also version 1.1.6):

>>> from pyalsa import alsaseq
>>> int(alsaseq.SEQ_EVENT_NOTE)
5

I assume the disparity means this a build/packaging error.

I can use the Github version, so this is not urgent for me, but thought I should report it.
