Version 0.48.1

[TheElementalOfDestruction]

v0.48.1

• Added an option (-s, --stdin) to the command line to take an MSG file from stdin. This allows the user to pipe the MSG data from another program directly instead of having to write a middleman that uses the extract-msg library directly or having to write the file to the disk first.
• Changed main function to allow for manual argument list to be passed to it.
• Added attributes to AttachmentBase for creation and modification time. These can be accessed through createdAt or creationTime and lastModificationTime or modifiedAt.
• Changed OleWriter tests to output the name of the test file being done if an error occurs.
• Added tests for some command line stuff.
