startup time is very long

[alecGraves]

The startup time for this utility is too long.

Startup time for vcs:

$ time vcs --version
vcs 0.3.0

real    0m0.170s
user    0m0.150s
sys     0m0.020s

Compared to bash:

$ time bash --version
GNU bash, version 5.1.16(1)-release (x86_64-pc-linux-gnu)

License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

real    0m0.002s
user    0m0.001s
sys     0m0.001s

Or even a python3 program:

$ time python3 -c 'import sys; print(sys.version)'
3.10.6 (main, Mar 10 2023, 10:55:28) [GCC 11.3.0]

real    0m0.016s
user    0m0.015s
sys     0m0.001s

And this is on some fairly ridiculous hardware:

$ time cat /proc/cpuinfo |  grep 'model name' | head -n1
model name      : 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz

real    0m0.002s
user    0m0.005s
sys     0m0.000s

It could be the python package structure.

A PR to improve that would probably be welcome.
