jsonld.to_rdf: Zeros not truncated for numeric values with negative exponent

[tripougnif]

Say value=0.97

Expected result: 9.7E-1

Actual result: 9.700000000000000E-01

Fix: replace

pyld/lib/pyld/jsonld.py

Line 3667 in 316fbc2

r'(\d)0*E\+?0*(\d)', r'\1E\2',

with

r'(\d)0*E\+?(-)?0*(\d)', r'\1E\2\3',

Of course, this is assuming something like 9.700000000000000+-E01 is not possible...

Thank you!
