feat: enable sub-64px dimensions

Description

Issue

This is the seventh Merge Request from the SVT-AV1-PSY team aiming to integrate our features into mainline SVT-AV1 under the oversight of Hassene Tmar and Faouzi Kossentini. This MR enables encoding of source media with dimensions smaller than 64x64px.

@hassount mentioned that this limitation was imposed intentionally in the past due to crashes encountered with small dimensions. We had a user report something like this to SVT-AV1-PSY's bug tracker, and I've included the fix in this commit. I'm not sure if this fixes encoding with small dimensions in all cases, but I haven't personally encountered any crashes since this fix was incorporated.
