Current tikaondotnet version susceptible to multiple security issues

[haus]

From looking at the security page on tika's project (https://tika.apache.org/security.html), it looks like there are 10 CVEs that affect Tika < 1.18. The issues range from local files being overwritten, OOMs, infinite loops and other DOS vulnerabilities. It would be awesome to update the tika version under the hood to 1.19.1 to mitigate these issues.

(also I'd be happy to help update the tika version)
