SRAL Level 1 products are reported erroneously as naming convention violations

[sustr4]

Describe the bug
Sentinel 3 SRAL Level 1 products are erroneously reported as violating the Sentinel 3 naming convention. This affects all SRAL Level 1 products, i.e., products with titles starting with S3?_SR_1_.

To reproduce
Steps to reproduce the behavior:

curl -JOn "https://apihub.copernicus.eu/apihub/odata/v1/Products('f29adb61-3929-4cfd-b205-626dfbd3e418')/\$value"
unzip S3A_SR_1_SRA_A__20220802T194015_20220802T203045_20220804T083726_3029_088_170______PS1_O_ST_004.zip
stac sentinel3 create-item S3A_SR_1_SRA_A__20220802T194015_20220802T203045_20220804T083726_3029_088_170______PS1_O_ST_004.SEN3 ./

Said procedure fails, full dump is shown bellow.

Expected behavior
One of two things should happen:

1. Processing should fail gracefully, reporting product type as recognized but unsupported, or, even better
2. SRAL Level 1 products should be properly recognized and supported.

Additional context
I am considering opening a separate feature request for this product type.

Any updates on this? I am also struggling with this particular naming convention on SR_1 products.
