Fix ncu_parser for different csv column count

[TKONIY]

My Environment

• ncu (Version 2023.1.0.0)
• nvcc (release 12.1, V12.1.66)
• driver version: 530.30.02
• hardware: NVIDIA A10

Bug report

When the original ncu_parser.py parses the output CSV file generated by ncu, it asserts the number of metrics of each row is 12. While in my setting it is 15, it skips all the lines.

gpudb-char-and-opt/report_parser/ncu_parser.py

Lines 146 to 147 in 0395d20

	if len(line) != 12:
	continue

Fix

While the number of metrics may differs in different ncu versions, a flexible way may be filtering the invalid row according to the actual metric number achieved from the first row.
