[BUG] Dlls from seamingly non-standard package structure are not downloaded

[ltmx]

Description

It seems that some files are not downloaded... probably due to folder structure from the nuget package.
What is desired (ignore the fact that I put the package at the root manually)

What I get After downloading with NugetForUnity, for all the packages cited below:

we only get two files from the root... and no runtime folder with dlls

• NuGet Package: LlamaSharp.Backend.CPU, LlamaSharp.Backend.CUDA11, LlamaSharp.Backend.CUDA12
• NuGetForUnity Version: 4.1.0
• Unity Version: 2023.2.19f1
• Operating System: Windows

Hi,
Should be resolved by #631
I hope I have some time this week to finish it up.
