You should be able to do the same with the latest LBT plugin but the method for creating the BRTDfunc modifier has changed a little. This is what it would look like using the Ladybug Tools SDK of the LBT 1.4 plugin:
from honeybee_radiance.modifier.material.brtdfunc import BRTDfunc
brtd_modifier_str = """
void BRTDfunc TestLaminate_front
10
0.113 0.139 0.163
0.596 0.651 0.557
0 0 0
.
0
9 0 0 0 0 0 0 0 0 0
"""
brtd_modifier = BRTDfunc.from_string(brtd_modifier_str )
Then you can assign that brtd_modifier
object to whatever honeybee object you want (Face, Aperture, Door Shade).
