Detect signals in background-removed spectra

1	signal_detection(xr, fdr.c = 0.01, stren.c = 200, wid.c = 5)

`xr`	A p*n data matrix of background-removed spectra, where n is the number of spectra, and p is the number of frequency channels.
`fdr.c`	A number between 0 and 1, which is the cutoff for FDR.
`stren.c`	A positive number for the cutoff of the strength of a signal.
`wid.c`	A positive number for the cutoff of the width of a signal.

A list containing the indices of spectra with detected signals, tim.index, and a matrix recording the peaks of signals, peaks.

res <- signal_detection(xr)
# xr is the matrix of background removed spectra
# xr can be obtained by background_removal function

head(res$tim.index)  ## check the first few time indices of signals
