Add getNoteTags, updateNoteTags and updateNote

getNoteTags returns [str ...] of tags for a given note (note: int)

updateNoteTags removes the existing tags and sets new tags

updateNote combines the old updateNoteFields and the new updateNoteTags

+*   **updateNote**
+
+    Modify the fields and/or tags of an existing note.
+    In other words, combines `updateNoteFields` and `updateNoteTags`.
+    Please see their documentation for an explanation of all properties.
+
+    Either `fields` or `tags` property can be omitted without affecting the other.
+    Thus valid requests to `updateNoteFields` also work with `updateNote`.
+    The note must have the `fields` property in order to update the optional audio, video, or picture objects.
+
+    If neither `fields` nor `tags` are provided, the method will fail.
+    Fields are updated first and are not rolled back if updating tags fails.
+    Tags are not updated if updating fields fails.
+
+    > **Warning**
+    > You must not be viewing the note that you are updating on your Anki browser, otherwise
+    > the fields will not update. See [this issue](https://github.com/FooSoft/anki-connect/issues/82)
+    > for further details.
