Noob instructions in README

Greetings, thanks for your work.

As a NOOB, I didn't know how to run the script. Although, it seems easy (perl get-all-project-issues.pl), it would have been nice to see that in the README.

Even so, when I issued that command, I got:

Can't locate LWP/UserAgent.pm in @inc (you may need to install the LWP::UserAgent module) (@inc contains: /etc/perl /usr/local/lib/arm-linux-gnueabihf/perl/5.28.1 /usr/local/share/perl/5.28.1 /usr/lib/arm-linux-gnueabihf/perl5/5.28 /usr/share/perl5 /usr/lib/arm-linux-gnueabihf/perl/5.28 /usr/share/perl/5.28 /usr/local/lib/site_perl /usr/lib/arm-linux-gnueabihf/perl-base) at get-all-project-issues.pl line 5. BEGIN failed--compilation aborted at get-all-project-issues.pl line 5.

Once, I solve that, I would have expected that the script would require some arguments such as ProjectId, BaseURL, and PRIVATEToken. However, I see that one must edit the script to provide these. That's fine, but the README ought to mention that.

Thanks again for your work!
