Subject: [PATCH] generate-bindings: allow to use local files

shacl2code needs to download the following URLs during build time:
 - https://spdx.org/rdf/3.0.1/spdx-model.ttl
 - https://spdx.org/rdf/3.0.1/spdx-json-serialize-annotations.ttl
 - https://spdx.org/rdf/3.0.1/spdx-context.jsonld

There are a lot of package build tools that do not allow to download
a file during the build. So provide a way to use local file:
If the environment variable SHACL2CODE_SPDX_DIR is defined, load
the SPDX model and SPDX context from the directory specified by this
environment variable.
