Description
Describe the issue
When VEP adds the LoF_info annotation, it does not sanitize its output and allows commas in the LoF_info subfield. For example:
[...]|PERCENTILE:0.7,GERP_DIST:-366.3[...]MAX_ORF:-698.745,GA|frameshift_variant[...]
This makes it impossible to split the consequences by transcript and variant, programs that are designed to extract and query VEP annotations fail (such as bcftools +split-vep).

Proposed solution
Replace commas and other special characters in plugins' outputs with the corresponding percent encoded characters, as recommended by the VCF specification v4.3 in section 1.2 (http://samtools.github.io/hts-specs/VCFv4.3.pdf).
