Bump vulnerable dependency on jackson-mapper-asl (CVE-2019-10172)

Parseq depends on jackson-mapper-asl, which has not been updated for many years and has been since deprecated, moved to jackson-databind under FastXML.

This library has a serious CVE that can only be addressed by migrating from jackson-mapper-asl to jackson-databind module at a later version (preferably [2.13.2.2](https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.13.2.2))

This ticket is for doing this migration with Parseq. Because Restli client depends on Parseq, this dependency bubbles up to anyone depending on Rest.li client as well.

Inspect Parseq's dependency declarations and usages of jackson-mapper-asl first, then run the existing test suite to identify migration impact. Done means Parseq uses jackson-databind at the requested later version and the vulnerable jackson-mapper-asl dependency no longer bubbles up to Rest.li clients.
