Adstex

This PR fixes a bug of bib file not being updated when using adstex with bibtexparser v1.4.1. Thanks to stevenrjanssens for reporting the issue.

What's Changed
* make compatible with bibtexparser v1.4.1 by yymao in https://github.com/yymao/adstex/pull/39
* make lower case -p acceptable by yymao in https://github.com/yymao/adstex/pull/40


**Full Changelog**: https://github.com/yymao/adstex/compare/v0.5.0...v0.5.1

A new option `--disable-ssl-verification` is introduced to temporarily disable the verification of SSL certification. This option can be handy when ADS has just updated their SSL certification while your local SSL certification installation has been updated (which will result in a `SSLCertVerificationError`).

Note that with this option, your ADS API key may be vulnerable to a man-in-the-middle attack. You can generate new ADS API key on [ADS website](https://ui.adsabs.harvard.edu/user/settings/token) if you think your API key may have been compromise.

Thanks to kirxkirx for suggesting this feature in 33.
