New karma tests suite

[kalwalt]

As mentioned in this issue #122 i'm testing Qunit with Karma. I think i will add only a basic implementation for now and then maybe also adding to actions github.

Issues

i need to add a full path for the camera_para.dat resource instead of:
"./camera_para.dat"
i need to change to:
"./base/tests/camera_para.dat";
I will ask in the karma or qunit issues to know what i'm doing wrong.

The CI action fails to make the test because:

key: Linux-npm-5d31f7d7bcd3af2e8b82a4cf4dce74189d9cc2f828919370e25d735311741353
Cache not found for input keys: Linux-npm-5d31f7d7bcd3af2e8b82a4cf4dce74189d9cc2f828919370e25d735311741353

maybe the actions/cache need a different setup.
See https://github.com/actions/cache/blob/main/examples.md#node---npm

POST EDIT: This wasn't the issue. The reason was in karma.conf.js file singleRun: false, option made to not exit the application and that's why action github was waiting forever (see #126 (comment)). So the cache message is correct.
