Cannot set virtual indicator realm individually

[huard]

Setup Information

• Xclim version: dev
• Python version: 3.10

Description

The realm of individual indicators in yaml files is ignored. It is systematically overwritten by the global realm attribute, and it it doesn't exist, the default atmos.

Steps To Reproduce

Load the following yaml file with xc.core.indicator.build_indicator_module_from_yaml and inspect each indicator's realm. It will be set to seaIce.

realm: seaIce

indicators:
  jetstream:
    base: jetstream_metric_woollings
    src_freq: M
    realm: atmos
    keywords: spatial_reduction
  sea_ice_extent:
    base: sea_ice_extent
    realm: ocean
    src_freq: M
    keywords: spatial_reduction
