NCrontabViewer throwing InvalidCastException

This line and this line each fail to be casted to ISupportInitialize. Looks like ToolStripStatusLabel no longer inherits from that interface in .NET 5.0. Commenting out both the lines allows the program to run just fine.

Thanks for reporting this! Feel free to send a PR if you wish to receive credit otherwise I'll close this issue when I get round to fixing it.

I'm not sure the best approach to fixing it, as I'm not terribly familiar with what ISupportInitialize does. I do know that it seems to work fine with the line omitted; I see a status bar with "Ready" at the bottom of the window. If that's the best solution, I'll happily remove the two offending lines in a PR.

I put a PR in anyway for you to merge at your discretion. Thanks!
