Hardcoded style overrides height/width props

[siegerts]

Hi @damienroche,

Thanks for the lib!

In trying to adjust the height/width of the BlurHashImage, I noticed that the hardcode 100% values in the subcomponents are not respecting the height/width props.

Wondering what your thoughts are on passing those provided props into the style definitions?

Something like -

:style="`height: ${height}px; width: ${width}px; position: absolute; top: 0; left: 0; right: 0; bottom: 0;`"

instead of

style="height: 100%; width: 100%; position: absolute; top: 0; left: 0; right: 0; bottom: 0;"

I'm happy to submit a PR if it works for you.

Thanks!
