Verify and redownload corrupted .nupkg files

[JosueNina]

This update ensures that downloaded .nupkg files are not corrupted before use. If a file is found to be corrupted, it is automatically deleted and re-downloaded to maintain integrity. The verification is performed using zipfile.testzip(), which checks for issues in the ZIP structure of the NuGet package

Closes #505

---------------------- Next one doesn't have an issue created, but this is what we need: You can download data using the cli with the `lean data download` command. See for instance this dataset <https://www.quantconnect.com/datasets/algoseek-us-equities> to download equity data (click on CLI for examples), you can download trade daily data for AAPL and MSFT equities with this command: lean data download ` --dataset "US Equities" ` --data-type "trade" ` --ticker "AAPL, MSFT" ` --resolution "daily" Some datasets are on a "pending" state (see the QCDataset class) which means we haven't made it public yet. For instance the "US Future Universe <https://www.quantconnect.com/datasets/quantconnect-us-future-universe>" dataset is pending. If you try to download data from that dataset, the cli will tell you it can't find it. For example, run lean data download then select "QuantConnect" and then "Financial Market Data" and make sure "US Future Universe" is not listed (because it's pending). What we want is to have an env variable and a constant to enable listing pending datasets (see for instance the `API_BASE_URL` constant in `constants.py`). It should default to false. If true, you should see the "US Future Universe" dataset (and eny other pending datasets) listed. Let me know if you understand or ask me anything
