* fetch salary data from LinkedIn (if it exists)

thanks frzkhan

* fix LinkedIn endpoint bug
* add LinkedIn company url to output

LinkedIn has a 1000 job limit & the code should be able to fetch them all. Although runtime is somewhere around 5-10min as LinkedIn is not multi-threaded to avoid their rate limiting.

* Add Glassdoor, 900 job limit. should be able to fetch sub 30s. Put `results_wanted=900` and try it out.
* Glassdoor supports many of the same countries as Indeed, but it's a smaller subset; look at the readme. It uses the `country_indeed` parameter as well.

Note: it will only hit near 900 if there's that many jobs; many of my regular searches, I'd get 100-400 results


* zip recruiter bug fix
thanks KilovoIt

* use ziprecruiter API instead of hitting their main page. You should be able to get unlimited jobs (tested with 1000 jobs). There is a 5s delay in between each request as 5s is ZipRecruiter's rate limiting rule
