Add metadata to matrix for ComplexHeatmap

1	add_matrix_metadata(m, gr, target_name, signal_name)

`m`	The matrix to update.
`gr`	A GRanges corresponding to the regions to subset the coverages. All the regions must have the same width (see ?GenomicRanges::resize to resize regions).
`target_name`	The name of the center region of the matrix. Will be shown at the bottom of the matrix.
`signal_name`	The name of the matrix. Will be shown on top of the matrix.

A normalizedMatrix ready to be used with ComplexHeatmap.

gr <- import_peaks(get_demo_peaks_file())
m <- coverage_2_matrix(cov[[1]], gr)
m <- add_matrix_metadata(m, gr, "TSS", "Peaks")
