ENH: Have names to the inline images

[Miksus]

Is your feature request related to a problem? Please describe.
The inline images are attached as "noname":

or more specifically, without a name. For library users that use it to send emails to clients, this may not be nice as that might sound unprofessional and suspicious.

Describe the solution you'd like
An option to give a name to the inline-image. Possibly have another name by default than "noname".

Describe alternatives you've considered
Serve the image from a server.

There is also one more alternative by passing the image as dict:

from pathlib import Path

email.send(
    receivers=[...],
    subject="Example",
    html='''
        <p>Image (PNG):</p>
        <br>{{ dict_image }}
    ''',
    body_images={
        'dict_image': {
            "content": Path("image.png").read_bytes(),
            'subtype': 'png',
            'maintype': 'image',
            'filename': 'a_media.png'
        },
    }
)

Is there a way to still embed inline without it appearing as an attachment in the email list view?
