org-odt.el: Allow images to be anchored as characters

* lisp/org-odt.el (org-odt-entity-frame-styles): Add frame params
for images that are anchored as character.
(org-export-odt-format-image): Handle new anchor type
"as-char".
(org-export-odt-default-image-sizes-alist): Misc. change.
(org-export-odt-format-formula): Misc. change.

With this change, one can use the below snippet to produce
images that are laid out side-by-side.
    #+ATTR_ODT: :width 7 :height 7 :anchor as-char
    #+header: :file foo.png
    [[./foo.png]]
    #+caption: bar
    #+ATTR_ODT: :width 7 :height 7 :anchor as-char
    #+header: :file bar.png
    [[./bar.png]]
