Solid biomass to hydrogen process (#1213)

* Added solid biomass to hydrogen, bioH2, process

* Add doc for new config

* add release notes

* enable bioH2 also without biomass spatially resolved

* Update doc/release_notes.rst

Co-authored-by: Fabian Neumann <fabian.neumann@outlook.de>

* Added overnight cost

 Upcoming Release
 ================
+
+* Add option to produce hydrogen from solid biomass (flag ``solid biomass to hydrogen``), combined with carbon capture
+
 * Fixed PDF encoding in ``build_biomass_transport_costs`` with update of tabula-py and jpype1
 
 * More modular and flexible handling of transmission projects. One can now add new transmission projects in a subfolder of `data/transmission projects` similar to the files in the template folder. After adding the new files and updating the config section `transmission_projects:`, transmission projects will be included if they are not duplicates of existing lines or other projects.
