python: nuget packages with hypens in their names cause import errors

[joprice]

Description

When generating python for a package like thoth-json-codec, the hypens rename in the package name, which triggers a syntax error:

 from fable_modules.thoth-json-codec.codec import (Codec_map, Codec_array, Codec_1, CodecRequireQualifiedAccess_Codec_string, CodecRequireQualifiedAccess_Codec_int)

Expected and actual results

Package names containing hyphens could be escaped as periods are:

• Thoth.Json.Core -> thoth_json_core
• thoth-json-codec -> thoth_json_codec

Mapping these symbols to the same character of underscore would prevent having two dependencies that only differ in symbols, so maybe another valid character could be chosen if it is a concern.
