support for large MSEED files

[xiansch]

Hi,

I am trying to run PhaseNet on some very large (3K MB+) data files that are downloaded in large chunks from IRIS. I am running into the problem:
"Error reading ../20180715_20180725/mseed/HV.UWB_20180715_20180725.mseed:
ObsPy can currently not directly read mini-SEED files that are larger than 2^31 bytes (2048 MiB). To still read it, please read the file in chunks as documented here: obspy/obspy#1419 (comment)"

The obspy link has a solution which is to read in chunks, which I suppose is not implemented in the native PhaseNet reader. Would it be possible to update this (or I can do it manually, if I can get pointers to which function to modify).

Thanks

Hi, I think it would be easier to save the data into multiple files. Weiqiang
