Return `TP53_loh: 1` when it's inferred from `TP53mut` and `TP53maxvaf`

When TP53_loh is inferred, the api still responds with 0

Current behavior:

It returns TP53loh: 0 even thought it should be inferred as TP53mut is 2 or more and it's maximum vaf is > 55%.

What should it return:

It should show: TP53_loh: 1, or add a new variable like: TP53_loh_inferred: 1

[juanesarango]

In the ipssm R package the behavior is that if input is TP53loh: 0 but it can be inferred, the output is TP53loh: 1
