Numpy file viewer

! Displaying very large arrays (e.g., size > 10,000,000) is not currently supported.

Display (binary) .npy or .npz files in VSCode.

Change log

Please refer to CHANGELOG.md.

Other Features

• Show array shape. [see gif]
• Table view for 2D/1D array. [see gif]
• Array slice. (In progress)
