decode_tlv() adds indentation in the beginning, with the expectation that the TLV will be printed on the line afterwards in a switch-case.
However, in the case of a container TLV the switch-case simply adds another level of indentation and calls decode_tlv() for the inner TLVs. This causes the first inner TLV to be printed with too much indentation and double '|'.
Fix that by printing "container" and a newline for container TLVs, so that the result is as follows: : values=0,0,0,0,0,0,0,0 | container | chmap-variable=FL,FR | chmap-variable=FL,FR,LFE | chmap-variable=FL,FR,FC
