Class to encode and decode data encoded with MSNumpress.
MSNumpress supports three encoding schemata:

Decodes a Base64 string to a vector of floating point numbers using numpress.
This code is obtained from the proteowizard implementation ./pwiz/pwiz/data/msdata/BinaryDataEncoder.cpp (adapted by Hannes Roest).
This function will first decode the input base64 string (with optional zlib decompression after decoding) and then apply numpress decoding to the data.
in | The base64 encoded string |
out | The resulting vector of doubles |
zlib_compression | Whether to apply zlib de-compression before numpress de-compression |
config | The numpress configuration defining the compression strategy |
throws | Exception::ConversionError if the string cannot be converted |

This code is obtained from the proteowizard implementation ./pwiz/pwiz/data/msdata/BinaryDataEncoder.cpp (adapted by Hannes Roest).
This function will first apply the numpress encoding to the data, then encode the result in base64 (with optional zlib compression before base64 encoding).
in | The vector of floating point numbers to be encoded |
result | The resulting string |
zlib_compression | Whether to apply zlib compression after numpress compression |
config | The numpress configuration defining the compression strategy |
