Using SeisIO to read metadata file (format of resp) with errors?

[OUCyf]

Hi~
I'm unable to read a metadata file (format of resp) in SeisIO. But it works in ObsPy, so I think the resp.file are not damaged.

With SeisIO in Julia:

julia> using SeisIO

"RESP.G1.53275.01.SHZ"

julia> Resp = read_meta("resp", xml)
ERROR: BoundsError: attempt to access 18-element Vector{Union{Nothing, CoeffResp, GenResp, PZResp, PZResp64}} at index [260]

With ObsPy in python:

>>> import obspy
>>> 
>>> st = obspy.read("./G1.53275.01.SHZ.D.2012.087.00.00.00.mseed")
>>> 
>>> tr = st[0]
>>> 
>>> inv = obspy.read_inventory("./RESP.G1.53275.01.SHZ")
>>> 
>>> pre_filt = [0.001, 0.005, 45, 50]
>>> 
>>> tr.remove_response(inventory=inv, pre_filt=pre_filt, output="DISP",
...                    water_level=60, plot=True)  

<obspy.core.trace.Trace object at 0x7f7f29199a90>
>>> 

and get an imagine:

RESP file here:
RESP.G1.53275.01.SHZ.zip

Thanks in advance~
