Empty string is returned for values longer than 512 characters

[erikvalkering-seequent]

It seems that the limit is hard-coded to 512. I have a registry value with more than 512 characters.

For example, the following code fragment would fail if the value is longer then the currently supported limit:

const value = vsWinReg.GetStringRegKey('HKEY_LOCAL_MACHINE', 'SOFTWARE\\Microsoft\\Windows\\CurrentVersion', 'ProgramFilesPath');
assert.notStrictEqual(value, '');
