support for gzipped csv

[daeho-ro]

I have added the gzip support, #39. Let say the file path is .../test.csv.gz.

1. I include the match string condition like "*.csv.gz" in the config file.
2. Since the table name is wrong, cut the base when it ends with .gz. As a result, the base is now test.csv and make the table name as test same as before.
3. Check if the path ends with .gz when the file open, then add one more step to unzip the gzipped file.

Here is the sample csv file. ``` > cat test.csv a,b,c,d,e 1,2,3,4,3 1,2,1,1,2 5,4,3,2,1 a,a,a,b,c ``` Let us gzip the file, ``` > gzip test.csv.gz ``` and then you can find the file is now gzipped. ``` > ls test.csv.gz ``` Now, do `steampipe query` and the result is here. ``` Welcome to Steampipe v0.16.4 For more information, type .help > select * from test +---+---+---+---+---+---------------------------+ | a | b | c | d | e | _ctx | +---+---+---+---+---+---------------------------+ | a | a | a | b | c | {"connection_name":"csv"} | | 5 | 4 | 3 | 2 | 1 | {"connection_name":"csv"} | | 1 | 2 | 1 | 1 | 2 | {"connection_name":"csv"} | | 1 | 2 | 3 | 4 | 3 | {"connection_name":"csv"} | +---+---+---+---+---+---------------------------+ ```

I have updated my code to deal with the BOM skip part.

Hey @daeho-ro , thanks for raising this PR! Just commenting to let you know this is on my radar to review tomorrow, sorry for the delay, I've been working through my backlog for the moment.

@daeho-ro Sorry for the long wait for the review, thanks for adding this new feature! We'll plan for a release in a new plugin version early next week.
