nlp-feature-extractors pypi source does not include requirements.txt and LICENSE - needed for conda feedstock

[rxm7706]

Describe the bug

• https://pypi.org/project/nlp-feature-extractors/#files
• https://files.pythonhosted.org/packages/e9/b4/bf6f6dea330cb5e7301d3b58bcfff8a631f3bcfbd5a56769691aad1729a0/nlp_feature_extractors-0.1.0.tar.gz

conda build nlp-feature-extractors using the recipe generated by grayskull pypi nlp-feature-extractors
