Allow flexible installation location of long-to-linked-pe (#128)

* Allow flexible installation location of long-to-linked-pe

* If already found on the PATH, use that path, else in src dir
* Also remove unneeded btllib version restriction in requirements.txt

* Remove hard-coded path to tigmint-make in run_tigmint_demo.sh

* Update CI

* Change python version for CI

* Use mamba for all CI
