Renderer MASA output metadata difference
# Basic info
<!--- Add commit SHA used to reproduce -->
- Float reference:
- Renderer (float): f40fa467
- Fixed point:
- Renderer (fixed): 3ea8505de
# Bug description
Using the renderer's meta input with multiple input formats and outputting into MASA produces metadata that differs clearly from the float reference.
Image below shows metadata azimuth and elevation angles (with direct-to-total energy ratio as alpha channel) and direct-to-total energy ratio for both metadata directions.

# Ways to reproduce
Using STV input:
```bash
IVAS_rend -q -if meta -i scripts/testv/mixed_mc714_foa_masa2_ism4.txt -fs 48 -of MASA1 -o renderer_test_short48_c1f32b7f0_float_0049_mixed_mc714_foa_masa2_ism4.wav_MASA1.wav
```
Another example using an OMASA item with one ISM and one MASA component:
```shell
IVAS_rend -q -no_delay_cmp -if meta -i scripts/testv/stvOMASA_1ISM_2MASA2TC48c.txt -fs 48 -of MASA1 -o 0058_stvOMASA_1ISM_2MASA2TC48c.wav_MASA1-no_delay_cmp.wav
```
resulting into the following metadata:

The contents of the renderer metafile `scripts/testv/stvOMASA_1ISM_2MASA2TC48c.txt` using the existing STV files is
```
stvOMASA_1ISM_2MASA2TC48c.wav
