Compatibility support for journal names with org-journal

[djhejna]

Currently the popular emacs package "org-journal" uses a naming convention of %Y%m%d (20190731) for entries. org-journal-list however defaults to %Y-%m%d.journal.org (2019-07-31.journal.org) and although the suffix (.journal.org) can be customized, the file name format can not be changed. If org-journal-list--start used a customize-able variable for the format of the journal entries, then the package would be compatible with org-journal. This would be a nice addition.
