Description
The iterator returned by text_bodies returns an object that is not necessarily a text element. But can become a text element.
Perhaps it might be better to have an iterator that returns a generic object that can be converted to text using functions such as those found in body_text (https://github.com/stalwartlabs/mail-parser/blob/65533d3faf6f147fa288fa30eae0bb4df80b2948/src/core/message.rs#L407C12-L407C21)
and perhaps make the body_text function generically available as a helper function rather than a method.
Alternatively include the text transforms of body_text to be included in the iterator of text_bodies so that the relevant text is returned.
What I found difficult about the current implementation is that an iterator using the text code returns "<html><p>I was thinking about quitting the “exporting” to focus just on the “importing”,</p><p>but then I thought, why not do both? ☺</p></html>" for .text_contents() rather than I was thinking about quitting the “exporting” to focus just on the “importing”, but then I thought, why not do both? ☺ which would seem a more natural return.
