Fix Tests on Windows

[trevorb1]

Description

In this PR I update otoole to fix failing tests on Windows.

Specifically this includes:

• Explicitly setting all int as int64 data types when the config file is first read in. Im not sure why, but on Windows pandas seems to set int as int32, while on Linux it will set it as int64 (or is just not concerned about int32 vs. int64). Anyways, int64 is explicitly set now
• Explicitly setting int64 for int datatypes in the results package (note, the config file dtypes are not accessible here)
• Explicitly setting int64 for read_strategies of solvers
• Specify the lineterminator argument as \n when writing to csv or datafiles, as Windows will default to \r\n. More information here
• Fix NamedTemporaryFile calls in the tests on Windows. As this Stack Overflow comment and this Python docs states, to open a NamedTemporaryFile on Windows, you must set delete=False and then explicitly close and delete the file. Therefore, I have wrapped all NamedTemporaryFile calls in tests in try finally blocks, where the finally code closes and deletes the temporary file.
• Adds Windows testing to the CI GitHub Action
