[BUG] --aq-mode 0 results in the encode aborting

[motbob]

Overview
With --aq-mode 0 as the only parameter, the encode aborts with no error message.

Branch
In which branch does the issue appear to be occurring?

• master
• testing

Reproduction
Steps to reproduce the behavior:

1. Obtain a 10-bit y4m (not sure if it needs to be 10-bit)
2. Do SvtAv1EncApp -i input0.y4m -b asdf.ivf --aq-mode 0

Expected behavior
The encode results in an output file larger than 0KB.

Platform (please complete the following information):

• Operating System: Windows
• I tested on various psy binaries and don't know the build details of some of them.

Version String (please complete the following information):

• SVT-AV1-PSY Encoder Lib v2.3.0-B

Additional context / Relevant Files
--aq-mode 0 appears to work fine in vanilla svt-av1.

Yeah, this is sadly an annoying behavior with --tune 2/3 where the encoder is supposed to abort:

I'm currently working on a way to disable SSIM-RD, or simply refuse the use of --aq-mode 0 when --tune 2/3 are active.
