Changes

Remove from list when updated to contract work page [https://contractwork.vipulnaik.com/worker.php?worker=Sebastian+Sanchez] and [https://github.com/vipulnaik/contractwork/blob/master/contributor-lists/sebastian-sanchez-list.mediawiki].

** Somewhere in the big picture, maybe talk about the two main bands of 5G: millimeter wave✔, which is faster but has less range, and sub-6GHz, which is quite similar to 4G LTE and only slightly faster.✔

** Then, in the various rows of full timeline where applicable, clarify whether the 5G rollout uses millimeter-wave or sub-6GHz✔/✘ (Sebastian: Not 100% complete. Probably with more time and research, blank sections could be filled)
