[BUG in HRTF interpolate]

[Kazusa-z]

Describe the bug
Hi, I'm getting an error when trying to barycentric interpolation for HRTF files in .sofa format.

To Reproduce

import slab

ari_obj = slab.HRTF('data/CIPIC/subject_003.sofa')
i_hrtf = ari_obj.interpolate(azimuth=0, elevation=0, method='barycentric')

Actual behaviour
The output of the minimal code example. For instance, in the example above:

ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (201,) + inhomogeneous part.

OS and Version:

• OS: win
• Version 1.1.5

Thanks for reporting this! I will look into it this week. My first impression is that this is due to differences in how the hrtf filters are organized in different sofa files. I remember coming across this issue in a different context with one of the hrtf databases.
