Resolves: https://jira.lyrasis.org/browse/FCREPO-3386

• Normalize the directory path when setting
• Close InputStream when loading custom BagProfile json

Testing

1. Start a fresh fedora repository, e.g. with fcrepo4-docker FEDORA_TAG=5.1.0 docker-compose up -d
2. Create a binary in the repository
3. Create a bag-config.yml for export

   bag-info.txt:
    Source-Organization: fcrepo-import-export
    Organization-Address: localhost
    External-Description: BagIt Bag

4. Run the exporter

   java -jar target/fcrepo-import-export-0.4.0-SNAPSHOT.jar --mode export --resource http://localhost:8080/fcrepo/rest --dir fcrepo-3386  --binaries --bag-profile beyondtherepository --bag-config bag-config.yml --user fedoraAdmin:secret3

5. Run the import prefixing the directory with ./

   java -jar target/fcrepo-import-export-0.4.0-SNAPSHOT.jar --mode import --resource http://localhost:8080/fcrepo/rest --dir ./fcrepo-3386  --binaries --bag-profile beyondtherepository --bag-config bag-config.yml --user fedoraAdmin:secret3

   a. I also tested against ./fcrepo-3386.tar, ../fcrepo-3386.tar, and ../fcrepo-3386. The Fedora repository was reset between each run to ensure the binaries were correctly uploaded by bringing down the docker container and starting a fresh version again.
