v0.7.0

Changes

• pushing CSV files with different delimiters now supported (e.g., your CSV can be semicolon or pipe delimited)
• pushing large files now works
• now guessing file encoding and including it in the descriptor so it is displayed correctly in the frontend
• init command rework - now using "data.js" library
• bug fixes
  • "get" command is back working with DataHub and GitHub datasets, e.g., you can do data get https://datahub.io/core/finance-vix or data get https://github.com/datasets/finance-vix
  • when pushing Excel files, CLI checks if provided sheet index exists and gives to user message if not
