Update LDENPointNoiseMapFactory.java - Increase Precision for Numeric Columns in forgeCreateTable Method

[IsotoCedex]

Description:
This change updates the precision of numeric columns from (5,2) to (9,2) in the forgeCreateTable method.

See acf9ae7

Reason for Change:
The previous precision (5,2) caused the error:
"Value too long for column 'HZ8000 NUMERIC(5, 2)'"
This issue typically occurs when the propagation distance exceeds 3000 meters, resulting in values that exceed the allowed range.

Proposed Fix:
Update the numeric(5,2) columns to numeric(9,2) for fields LAEQ, LEQ, and frequency-related columns (HZ*).
This ensures compatibility with larger numerical values generated in scenarios with significant propagation distances.

Impact:
Resolves the numerical precision issue for long propagation distances.
Prevents runtime errors when inserting large numerical values into frequency (HZ*) and acoustic level (LAEQ, LEQ) columns.

In the last version we switch to the REAL type
