[Feature request] Dump mode: Corese server write its content in a file at the end of execution

[MaillPierre]

Is your feature request related to a problem? Please describe.
I am currently working on a project where I am trying to generate a dataset of descriptions of endpoints using corese. However, a bug that will be described in another ticket makes the corese docker instance stop working for some reason.
I would like to be able to set several "save points" where I retrieve the state of the content of the server at specific intervals

Describe the solution you'd like
A setting in corese would indicate the name of the dump file where the server would write its content during a clean shutdown. The format can be any graph-supporting format, such as NQuads or TriG
(How I would add this feature to my application is my problem)

Describe alternatives you've considered
I currently use a CONSTRUCT { GRAPH ?g { ?s ?p ?o } } WHERE { GRAPH ?g { ?s ?p ?o } } to retrieve the content of the server. However, the aforementioned bug makes such requests fail without explanation.

Additional context
Using image wimmics/corese at the latest version
