Decompress the samples from the provided DataView and return an array of the decompressed values. Only 16 bit short, 32 bit int, 32 bit float and 64 bit double along with Steim1 and Steim2 are supported.
(number)
compression format as defined in SEED blockette 1000
(DataView)
input DataView to be decoded
(number)
the number of samples that can be decoded from array

Decode the indicated number of samples from the provided byte array and return an integer array of the decompressed values. Being differencing compression, there may be an offset carried over from a previous data record. This offset value can be placed in bias, otherwise leave the value as 0.

b
(boolean)
if true, dataView is little-endian (intel byte order)

(number)
the first difference value will be computed from this value.
If set to 0, the method will attempt to use the X(0) constant instead.
