Update 3rd party libraries

[aspark21]

They haven't been updated in 4 years
https://github.com/IMSGlobal/caliper-php

Not sure about the log expander, it's not even a published repository anymore
But after some digging found this being the last standalone version - https://github.com/Mishkin2015/Moodle-Log-Expander
Mishkin2015/Moodle-Log-Expander@4a60cc8#diff-0730bb7c2e8f9ea2438b52e419dd86c9R2
So now need to look at https://github.com/xAPI-vle/moodle-logstore_xapi
This was the initial merge in, if it helps track what needs updating - xAPI-vle/moodle-logstore_xapi@b19e342
