Description

julia> findlocalmaxima([1 2 3 2 1])
1-element Vector{CartesianIndex{2}}:
 CartesianIndex(1, 3)

julia> findlocalmaxima([1 2 3 3 1])
CartesianIndex{2}[]

I'm not sure whether it is a bug or I need to handle this case outside findlocalmaxia

Research direction

Locate the implementation of findlocalmaxima and any existing tests, then reproduce the two Julia examples from the issue. Read how repeated or plateau peaks are currently handled and establish the expected result for [1 2 3 3 1]. Done means the behavior is specified by a regression test and the function handles the repeated peak consistently.
