Describe the bug

A clear and concise description of what the bug is.
Value tokens like 0003530043 and 00126 are converted to text without their leading zeros.

Expected behavior

Using CLI option --no-type-inference or --type-hint-header with a column that hints text, then the value 0003530043 should be converted as 0003530043 rather than 3530043.

To Reproduce

Steps to reproduce the behavior:

1. Given this CSV called zero.csv:

column1, column2-text
123, 0123
0123, 123
123, 0123

2. And the CLI: sqlitebiter --type-hint-header -o zero.sqlite file zero.csv
3. Then after sqlite3 zero.sqlite:

.header on;
select * from zero;

4. I expect you will see:

column1|column2-text
123|123
123|123
123|123

5. Verify the table's structure:

CREATE TABLE IF NOT EXISTS 'zero'([column1] INTEGER, [column2-text] TEXT);
