add glitch to failure classes

     \item The glitch acts as additional spacing between what is perceived as two data tokens, injecting an additional one into the pipeline. This would also result in a \emph{token count failure} (and potentially a \emph{value failure})
     \item The glitch changes the value of a data line and thus creates a \emph{value failure} or, in a DI-coding, a potential \emph{coding failure}

 These failure modes are in accordance with the potential states of a circuit from \cite{bainbridgeGlitchSensitivityDefense2009}; we thus reuse the same failure classification as already presented in \cite{behalExplainingFaultSensitivity2021}.
