deal with malformed TAL

If you need to deal with malformed TAL onsets, durations or annotations somehow, the irrecoverable errors that get thrown are not very helpful.

Two errors seen in the wild are Float64 parse errors here

EDF.jl/src/read.jl

Lines 156 to 157 in f370e83

	onset_in_seconds = flipsign(parse(Float64, timestamp[1]), sign)
	duration_in_seconds = length(timestamp) == 2 ? parse(Float64, timestamp[2]) : nothing

and here

EDF.jl/src/read.jl

Line 167 in f370e83

error("starting byte of a TAL must be '+' or '-'; found $sign")

(and there are probably be other ways that TAL parsing can go wrong).

Maybe a good way would be to add an option to not throw on TAL parse errors, and instead return a list of structured errors that tell you the offending byte range, alongside the requested EDF, to make it easier to fix the offending EDF bytes.
