0.2.0

added toasts for file open errors and successful saves

added showSaveFilePicker() for browsers that support it

saved files are now gzip compressed and saved as .tldz

.tldr and .tldz files can both be opened

4 options:

the .html is a standalone webapp that runs on whatever browser you want

the .zip contains a standalone windows app (.exe) that uses the built-in webview2 from windows 10/11

the other two are installers that will check if you have webview2 and get that for you if you don't have it
