Add requests popup view in current directory

[happsie]

Open a popup view loading the files in the current directory (where wuzz was started). Select with up and down arrows and hit enter to load the request. Won't show directories

wuzz.mp4

Great feature, however the name "requests" is a bit confusing. Could you find a bit more specific and self describing name for this feature?

[happsie]

@asciimoo absolutely, I thought of renaming it but forgot before pushing. Would something like ListDirectoryView work? Im thinking since it's actually only listing the current working directory not filtering files. Maybe I should add a filter for .json and .curl files since those are the exported/imported options in wuzz?

[asciimoo]

ListDirectoryView sounds good to me. I wouldn't add filter by default, because it is possible to export files with different extension names.

Great, I'll modify my PR with changes discussed above. Thanks 🙏
