JSON parse error: Invalid value. at offset <number>

This is an error caused by removing (in #242) the code to handle float infinities (introduced in #85) as requested in #208.
This becomes effectively a breaking change because existing json may have been written using e.g.

"edges": [
    15.0,
    20.0,
    25.0,
    30.0,
    40.0,
    50.0,
    60.0,
    120.0,
    Infinity
]

What we should do is allow but warn on use of these, as is done in the schema validator.
