Code cannot handle changes to downloaded file paths

[SolomonShorser-OICR]

For Release 76, Orthologs_HCOP.tar.gz was unzipped and untarred as a set of nested directories containing Orthologs_HCOP.
The full path is " target4/famlib/dev/PANTHER16.0/lib_16.0/ftp/Orthologs_HCOP"

Unfortunately, the application (class: org.reactome.release.orthopairs.OrthologyFileParser, method: parsePantherOrthologFiles) can't handle this.

release-orthopairs/src/main/java/org/reactome/release/orthopairs/OrthologyFileParser.java

Line 39 in c75f7be

BufferedReader br = new BufferedReader(new FileReader(extractedPantherFile));

Immediate solution was to just copy target4/famlib/dev/PANTHER16.0/lib_16.0/ftp/Orthologs_HCOP to the application's root directory, but a better long-term solution is needed. Preferably in the application, as it's file-handling looks fragile and prone to failure, but a fix in the Jenkinsfile or in the bash script that run the application might be OK.
