Incorrect ParseQuery logick

[valodzka]

ParseQuery in in collector.go incorrectly handles case when there are params before and after query

clickhouse-bulk/collector.go

Line 315 in b34e73c

if eoq >= 0 {

It might cause incorrect results or panic: runtime error: slice bounds out of range depending on params length.

Instead of

if eoq >= 0 {
			q = queryString[i+6 : eoq+6]
			params = queryString[:i] + queryString[eoq+7:]
}

It should be:

if eoq >= 0 {
			q = queryString[i+6 : i+eoq+6]
			params = queryString[:i] + queryString[i+eoq+7:]
}

Example of problematic string:
queryString = "a=11111111111111111111111111111&query=insert into x format fmt&a=1"
