This function reports the HEADER fields from a Heidelberg format
(.fh) ring-width file. The header fields are harvested from the .fh-file by
the read_fh() function, which stores the HEADER fields from the .fh file
as attributes of the data.frame with the measurement data it returns.
Examples
Doel1 <- system.file("extdata", "DOEL1.fh", package = "fellingdater")
Doel1_trs <- read_fh(Doel1, verbose = FALSE)
fh_header(Doel1_trs)
