Enums filtering support

[duhapunk]

Hello again! I noticed that your lib doesn't support enums. I fixed it like this:

• https://github.com/Kusumoto/PrimeNG.TableFilter/blob/master/PrimeNG.TableFilter/Core/LinqOperator.cs line 244
  if (propertyType == typeof(bool) || propertyType == typeof(bool?) || propertyType.IsEnum)
• https://github.com/Kusumoto/PrimeNG.TableFilter/blob/master/PrimeNG.TableFilter/Utils/ObjectCasterUtil.cs line 85

if (property.PropertyType.IsEnum)
{
     Enum.TryParse(property.PropertyType, value.ToString(), true, out var result);
     return result; // additional checks required
}

Works for me, @Kusumoto Could you release the fix?

I already try, it work but TryParse method just work for .NET Standard 2.0 only.

This is the major change because after support this I'll obsolete .NET Framework support.

Did you try "manual" TryParse ? Something like this

try
{
   var val = Enum.Parse(property.PropertyType, value.ToString(), true);
   var result = Convert.ChangeType(val, property.PropertyType);
   // additional checks required
   return result;
}
catch (Exception ex)
{
   // do some stuff
   return null;
}

Enum filtering would be great, if this could be incorporated :)
