Attiny and VescUartControl SRAM issue. CRC16 table using too much memory

Hey, So currently I have an Attiny87 + NRF24L01 to send Nunchuk values to VESC. The VescUartControl library uses too much SRAM for the Attiny87. This is due to the crc16() function in crc.cpp which uses a very large hash table. What is the purpose of this table and how can I make this smaller in memory?
