Added support for encrypted identifiers to tr-manual-enricher-pull-identifiers command.
- Now that this command is using Sombra to decrypt request identifiers, you may need to provide the --sombraAuth argument. It's required when using self-hosted Sombra, but not for multi-tenant.
```
Before:
  yarn tr-manual-enricher-pull-identifiers --auth=$TRANSCEND_API_KEY  \
    --actions=ERASURE \
    --file=/Users/michaelfarrell/Desktop/test.csv

Now:
  yarn tr-manual-enricher-pull-identifiers --auth=$TRANSCEND_API_KEY  \
    --sombraAuth=$SOMBRA_INTERNAL_KEY \
    --actions=ERASURE \
    --file=/Users/michaelfarrell/Desktop/test.csv
```

Added support for encrypted identifiers to tr-request-export command.

Now that this command is using Sombra to decrypt request identifiers, you may need to provide the --sombraAuth argument. It's required when using self-hosted Sombra, but not for multi-tenant.

Before:
  yarn tr-request-export --auth=$TRANSCEND_API_KEY  \
    --actions=ERASURE \
    --file=/Users/michaelfarrell/Desktop/test.csv

Now:
  yarn tr-request-export --auth=$TRANSCEND_API_KEY  \
    --sombraAuth=$SOMBRA_INTERNAL_KEY \
    --actions=ERASURE \
    --file=/Users/michaelfarrell/Desktop/test.csv

Added support for encrypted identifiers to tr-request-restart command, used only when --copyIdentifiers argument is specified.
- Now that this command is using Sombra to decrypt request identifiers, you may need to provide the --sombraAuth argument. It's required only when using --copyIdentifiers AND self-hosted Sombra, but is otherwise not required.
```
Before:
  yarn tr-request-restart --auth=$TRANSCEND_API_KEY \
    --statuses=COMPILING,APPROVING --actions=ERASURE --copyIdentifiers=true

Now:
  yarn tr-request-restart --auth=$TRANSCEND_API_KEY \
    --sombraAuth=$SOMBRA_INTERNAL_KEY \
    --statuses=COMPILING,APPROVING --actions=ERASURE --copyIdentifiers=true
