Remove range overlaps, fix some range specifications (#930)

* Drop some clearly redundant bounds

* Fix RUSTSEC-2020-0091 - the version specification was incorrect, marking 1.0.0 as fixed while in reality it was not

* Fix RUSTSEC-2018-0004: presumably any updates to 0.3.x series would also get the fix, it would not be isolated to 0.3.2

* Fix incorrectly defined, overlapping ranges in RUSTSEC-2020-0080 and RUSTSEC-2019-0035
