~1. Add H4 renorm~ (2443f38491f658f593e936a53f36ca03b6856b92) 2. Add norm_histone_value as output 3. Make apply_sample_offset and histone_normalization more analogous (maybe)? 4. Add QC plots to processing (spec [here](https://docs.google.com/document/d/1UpAMWcDz8nDR8figmfcKS26w0Xk-WedwIv3M_uqtp90/edit))
