Enhance opening and importing files from disk

[pleonex]

Creating a BinaryFormat from a file on disk is painful because it needs to be done in a long line or two lines:

var fileStream = DataStreamFactory.FromDisk(path, FileOpenMode.Read);
using var binary = new BinaryFormat(fileStream);

We could create a constructor for BinaryFormat for its basic case of passing a path and the open mode.

• [x] Create API in Node to change / replace format with file content
