show tests_preview_facet.png in PR comment, link to tests_all_facet.png

Since https://github.com/tdhock/atime/commit/ea4103f797aac2dbcae5c6858f9cc29b386d87a6 there is an output of a new image file, tests_preview_facet.png which only shows the 4 tests with the most significant differences between HEAD and min. this is available using current atime on CRAN. @Anirban166 can you please modify the PR comment so that tests_preview_facet.png is shown, but then when you click on it, you can see tests_all_facet.png ?

Done! (a while ago) You can see it working here, but why is tests_preview_facet.png horizontally stretched? (you can download the zip containing the results and check the same file to verify it's an issue with the image itself)

It looks a bit weird, but if you're fine with it then I can send a PR to data.table today to update my action with this feature and #36 combined. Otherwise I'll send it after you've fixed that, just let me know!

which only shows the 4 tests with the most significant differences between HEAD and min.

Just my take, but I think 3 tests might be better

thanks! the "horizontally stretched" issue was because the width was based on the total number of test cases, not the number of tests shown in the preview PNG. I won't publish another atime to CRAN for a while, but please do submit a data.table PR with your new changes. 3 tests instead of 4? that can be configured by defining N.tests.preview in atime/tests.R https://github.com/tdhock/binsegRcpp/commit/f70739aa3995b7f7553ccf4160afa370d5d5f9d7
