Build biomass transport costs from pre-extracted .csv instead of pdf

[bobbyxng]

Changes proposed in this Pull Request

• Previously, biomass transport costs were built from the JRC pdf report. (https://publications.jrc.ec.europa.eu/repository/bitstream/JRC98626/biomass%20potentials%20in%20europe_web%20rev.pdf)
• However this leads to issues on some cluster nodes, where Java dependencies are not properly referenced. Java is required for tabula-py to properly work.
• To avoid this, proposal to include the pre-extracted csvs to the data folder.
• Scripts and rules have been updated accordingly to drop the tabula-py dependency.

Checklist

• I tested my contribution locally and it seems to work fine.
• Code and workflow changes are sufficiently documented.
• Changed dependencies are added to envs/environment.yaml.
