Fixing biomass transport cost

[yerbol-akhmetov]

Changes proposed in this Pull Request

Good day. Here I propose changes to build_biomass_transport_costs.py file to fix the error that happens when biomass_transport is set true in the config. I have uploaded the error. It is related to utf-8 encoding, in particular, the error happens due to EUR sign. I run my code in the windows machine. The error is resolved by explicitly defining encoding as cp1252 which is a windows compatible encoding and an extension of latin-1 encoding. After I have fixed the code, I have checked the resulting csv. The resulting biomass transport costs coincides with the supplementary material in Liza's paper on "Mitigating heat demand ...".

Checklist

• I tested my contribution locally and it seems to work fine.
• A release note doc/release_notes.rst is added.

With the currently suggested changes, the script cannot be compiled on Linux. We're working on a fix.

Hello, @martacki. I have added encoding based on the OS. For Windows it is cp1252, while for Linux and MacOS it is None, because it works fine without it (while cp1252 causes issue for Linux).

Tested on Linux, seems to run.

The script is furthermore not touched with the default config configuration, only when biomass_transport = True
