Typos inside the libraries

When doing the Debian QLI packaging for this project, I came across the following Lintian warnings. Please consider double-checking those words inside the source code.

X: audioreach-graphmgr: spelling-error-in-binary sesssion session [usr/lib/aarch64-linux-gnu/libagm.so.1.0.0]
N:
N:   Lintian found a spelling error in the given binary. Lintian has a list of
N:   common misspellings that it looks for. It does not have a dictionary like
N:   a spelling checker does.
N:
N:   If the string containing the spelling error is translated with the help of
N:   gettext or a similar tool, please fix the error in the translations as
N:   well as the English text to avoid making the translations fuzzy. With
N:   gettext, for example, this means you should also fix the spelling mistake
N:   in the corresponding msgids in the *.po files.
N:
N:   You can often find the word in the source code by running:
N:
N:    grep -rw <word> <source-tree>
N:
N:   This tag may produce false positives for words that contain non-ASCII
N:   characters due to limitations in strings.
