Compatibility with Pandas 2.0+

[DannyCollinson]

As of Pandas version 2.0, the append() method for DataFrames is deprecated, causing problems loading negative samples.

To Reproduce With pandas version 2.0+ installed,

from tdc.multi_pred import MTI
data = MTI(name = 'miRTarBase')
data = data.neg_sample(frac = 1)

causes AttributeError: 'DataFrame' object has no attribute 'append'

To Fix For now, you can run neg_sample() with pandas 1.5.3 or below, but compatibility with Pandas version 2.0+ will require replacing df.append() calls with calls to pd.concat().
