fix to disallow invalid characters in filenames

[ATorrise]

What It Does
Provides a fix for issue143 by throwing an error when using invalid filenames so the progress bar doesn't loop indefinitely from the unhandled case of emojis and other invalid characters in dataset names. Depends on zowe-cli PR 1831 - unit tests will fail until this PR is merged in.

How to Test
Tested with the following launch.json configurations

    {
        "type": "node",
        "request": "launch",
        "name": "ftp download ds",
        "program": "${workspaceFolder}/packages/cli/lib/main.js",
        "console": "integratedTerminal",
        "args": ["zos-ftp", "download", "data-set", <realTestingDataSetName>, "-f", "testing.txt^B", "--secure-ftp", "false"],
        "outputCapture": "std",
        "resolveSourceMapLocations": null
    }

Expected response: Data set downloaded successfully. testing.txt^B

        "args": ["zos-ftp", "download", "data-set", <realTestingDataSetName>, "-f", "testing.txt☻", "--secure-ftp", "false"],

Expected response: Command Error: Invalid file name. Please check the file name for typos.

        "args": ["zos-ftp", "download", "data-set", <realTestingDataSetName>, "-f", "testing.txt", "--secure-ftp", "false"],

Expected response: Data set downloaded successfully. testing.txt
